Redirect 301 www.www.example.com - linux

I'm using LAMP server, and I need to redirect requests like:
www.www.example.com to www.example.com and other variations like (wwww.example.com, etc)
I know I can do it in .htaccess, but I don't know the regular expression that I should use to represent all these possibilities.
Or there is any diferent approach, comming from the vhosts?

I like:
# force www IN URL
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
# END force www IN URL
Basically anything that's not www.example.com will get redirect 301'd.

See this article for implementing "wildcard subdomains." You're going to need to implement both an .htaccess and modifying the Vhosts.
http://www.easymodrewrite.com/example-subdomains
If you're interested in only limiting it to "www.www," "wwww.," and the other examples above, you can easily do so with some server-side coding (which makes it more flexible than implementing more .htaccess code). Just detect what the subdomain is, and redirect where you want.

Using name based virtual hosts in Apache you can do this:
<VirtualHost *:80>
ServerName example.com
ServerAlias wwww.example.com www.www.example.com [space seperated list]
Redirect / http://www.example.com/
</VirtualHost>
Redirect can take a parameter to specify the type of redirect.

.htaccess specific url redirect to another domain url [duplicate]

After looking on the internet for about an hour, I didn't find the answer to my question. So I'm searching with the wrong keywords or what I want is not possible.
What I want:
I have multiple domains with different extensions, for example:
mydomain.be
mydomain.nl
Now what I want is that the mydomain.be is redirected to mydomain.nl. The solution for this I have found on the internet and shown below, with the need of .htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mydomain.be$ [OR]
RewriteCond %{HTTP_HOST} ^www.mydomain.be$
RewriteRule (.*)$ http://www.mydomain.nl/$1 [R=301,L]
With this code, when you type mydomain.be you will be redirect to mydomain.nl. But also the URL in the addressbar is changed to mydomain.nl. What I want is to keep the URL in the addressbar mydomain.be.
So, mydomain.be:
keep URL
show content of mydomain.nl
How To?
It is possible to get it done via mod_rewrite but make sure mod_proxy is enabled in your Apache's httpd.conf. Once that is done enable mod_rewrite and .htaccess through httpd.conf and then put this code in your .htaccess under DOCUMENT_ROOT directory:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.be$ [NC]
RewriteRule ^ http://www.mydomain.nl%{REQUEST_URI} [L,NE,P]
Take note of flag P which is used for handling the proxy request.
Read more about flag: P in mod_rewrite
Another option without hassling with .htaccess would be to point both domains to the same document root or setting one domain as an alias for the other, depending on how you are able to configure your Apache. However, this has downsides:
If your content management system uses absolute URLs a user who clicks on mydomain.nl on a link will be directed to the mydomain.be domain (WordPress does this, as an example).
Search engines punish this behaviour by placing you further down on the search results. at least Google does, they have an interesting blog post about duplicate content. Not sure about competitors.
An example apache config could be:
<VirtualHost *:80>
ServerName mydomain.nl
ServerAlias mydomain.be
DocumentRoot /var/www/mydomain.nl/htdocs
</VirtualHost>

Https is not working properly. Few pages are not working with https [duplicate]

I'm trying to redirect all insecure HTTP requests on my site (e.g. http://www.example.com) to HTTPS (https://www.example.com). How can I do this in .htaccess file?
By the way, I'm using PHP.
The Apache docs recommend against using a rewrite:
To redirect http URLs to https, do the following:
<VirtualHost *:80>
ServerName www.example.com
Redirect / https://www.example.com/
</VirtualHost>
<VirtualHost *:443>
ServerName www.example.com
# ... SSL configuration goes here
</VirtualHost>
This snippet should go into main server configuration file, not into .htaccess as asked in the question.
This article might have come up only after the question was asked and answered, but seems to be the current way to go.
Update: Although this answer has been accepted a few years ago, note that its approach is now recommended against by the Apache documentation. Use a Redirect instead. See this answer.
RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
I'd recommend with 301 redirect:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
As I was saying in this question, I'd suggest you avoid redirecting all HTTP requests to their HTTPS equivalent blindly, as it may cause you a false impression of security. Instead, you should probably redirect the "root" of your HTTP site to the root of your HTTPS site and link from there, only to HTTPS.
The problem is that if some link or form on the HTTPS site makes the client send a request to the HTTP site, its content will be visible, before the redirection.
For example, if one of your pages served over HTTPS has a form that says <form action="http://example.com/doSomething"> and sends some data that shouldn't be sent in clear, the browser will first send the full request (including entity, if it's a POST) to the HTTP site first. The redirection will be sent immediately to the browser and, since a large number of users disable or ignore the warnings, it's likely to be ignored.
Of course, the mistake of providing the links that should be to the HTTPS site but that end up being for the HTTP site may cause problems as soon as you get something listening on the HTTP port on the same IP address as your HTTPS site. However, I think keeping the two sites as a "mirror" only increases the chances of making mistakes, as you may tend to make the assumption that it will auto-correct itself by redirecting the user to HTTPS, whereas it's often too late. (There were similar discussions in this question.)
This is the html redirect approach it works but not the best.
<meta http-equiv="Refresh" content="0;URL=https://www.example.com" />
PHP approach
<?php
function redirectTohttps() {
if ($_SERVER['HTTPS']!="on") {
$redirect= "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
header("Location:$redirect");
}
}
?>
.htaccess approch
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
copied from:
www.letuslook.org
I found out that the best way for https and www on domain is
RewriteCond %{HTTPS} off
RewriteCond %{HTTPS_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]
I like this method of redirecting from http to https. Because I don't need to edit it for each site.
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
Using the following code in your .htaccess file automatically redirects visitors to the HTTPS version of your site:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
If you have an existing .htaccess file:
Do not duplicate RewriteEngine On.
Make sure the lines beginning RewriteCond and RewriteRule immediately follow the already-existing RewriteEngine On.
The best solution depends on your requirements. This is a summary of previously posted answers with some context added.
If you work with the Apache web server and can change its configuration, follow the Apache documentation:
<VirtualHost *:80>
ServerName www.example.com
Redirect "/" "https://www.example.com/"
</VirtualHost>
<VirtualHost *:443>
ServerName www.example.com
# ... SSL configuration goes here
</VirtualHost>
But you also asked if you can do it in a .htaccess file. In that case you can use Apache's RewriteEngine:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L]
If everything is working fine and you want browsers to remember this redirect, you can declare it as permanent by changing the last line to:
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
But be careful if you may change your mind on this redirect. Browsers remember it for a very long time and won't check if it changed.
You may not need the first line RewriteEngine On depending on the webserver configuration.
If you look for a PHP solution, look at the $_SERVER array and the header function:
if (!$_SERVER['HTTPS']) {
header("Location: https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
}
This is the proper method of redirecting HTTP to HTTPS using .htaccess according to GoDaddy.com. The first line of code is self-explanatory. The second line of code checks to see if HTTPS is off, and if so it redirects HTTP to HTTPS by running the third line of code, otherwise the third line of code is ignored.
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
https://www.godaddy.com/help/redirect-http-to-https-automatically-8828
Add the following code to the .htaccess file:
Options +SymLinksIfOwnerMatch
RewriteEngine On
RewriteCond %{SERVER_PORT} !=443
RewriteRule ^ https://[your domain name]%{REQUEST_URI} [R,L]
Where [your domain name] is your website's domain name.
You can also redirect specific folders off of your domain name by replacing the last line of the code above with:
RewriteRule ^ https://[your domain name]/[directory name]%{REQUEST_URI} [R,L]
Do everything that is explained above for redirection. Just add "HTTP Strict Transport Security" to your header. This will avoid man in the middle attack.
Edit your apache configuration file (/etc/apache2/sites-enabled/website.conf and /etc/apache2/httpd.conf for example) and add the following to your VirtualHost:
# Optionally load the headers module:
LoadModule headers_module modules/mod_headers.so
<VirtualHost 67.89.123.45:443>
Header always set Strict-Transport-Security "max-age=63072000; includeSubdomains; preload"
</VirtualHost>
https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security
To redirect all http requests to https , you can use :
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [NE,L,R]
If mod-rewrite isn't enabled and you are on apache 2.4, you can also use a Redirect inside if directive to redirect http requests to https .
Apache 2.4.
<if "%{HTTPS} !~ /on/">
Redirect / https://www.example.com/
</if>
If you are in a situation where your cannot access the apache config directly for your site, which many hosted platforms are still restricted in this fashion, then I would actually recommend a two-step approach. The reason why Apache themselves document that you should use their configuration options first and foremost over the mod_rewrite for HTTP to HTTPS.
First, as mentioned above, you would setup your .htaccess mod_rewrite rule(s):
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
Then, in your PHP file(s) (you need to do this where ever it would be appropriate for your situation, some sites will funnel all requests through a single PHP file, others serve various pages depending on their needs and the request being made):
<?php if ($_SERVER['HTTPS'] != 'on') { exit(1); } ?>
The above needs to run BEFORE any code that could potentially expose secure data in an unsecured environment. Thus your site uses automatic redirection via HTACCESS and mod_rewrite, while your script(s) ensure no output is provided when not accessed through HTTPS.
I guess most people don't think like this, and thus Apache recommends that you don't use this method where possible. However, it just takes an extra check on the development end to ensure your user's data is secure. Hopefully this helps someone else who might have to look into using non-recommended methods due to restrictions on our hosting services end.
Unless you need mod_rewrite for other things, using Apache core IF directive is cleaner & faster:
<If "%{HTTPS} == 'off'">
Redirect permanent / https://yoursite.com/
</If>
You can add more conditions to the IF directive, such as ensure a single canonical domain without the www prefix:
<If "req('Host') != 'myonetruesite.com' || %{HTTPS} == 'off'">
Redirect permanent / https://myonetruesite.com/
</If>
There's a lot of familiarity inertia in using mod_rewrite for everything, but see if this works for you.
More info: https://httpd.apache.org/docs/2.4/mod/core.html#if
To see it in action (try without www. or https://, or with .net instead of .com): https://nohodental.com/ (a site I'm working on).
Redirect 301 / https://example.com/
(worked for me when none of the above answers worked)
Bonus:
ServerAlias www.example.com example.com
(fixed https://www.example.com not found)
take this code to you .htaccess file
Redirect HTTP to HTTPS automatically
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
The above things are for the Apache server only. What if running PHP at tomcat?
So you can use PHP code, whether it is Apache/tomcat/Nginx etc...
if (!((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
$_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))){
$redirect = 'https://' . str_replace($_SERVER['SERVER_PORT'], 8443, $_SERVER['HTTP_HOST']) . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $redirect);
exit();
}
After lots of tries by considering without www and with www this works this
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} (www\.)?yourdomain.com
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Through .htaccess This will help.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
RewriteCond %{HTTPS} !=on
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
Also, Refer this for More Detail. How To Redirect Http To Https?
I found a method to force all pages of my site redirect from http to analog of pages on https that work for me.
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
This redirects all the URLs to https and www
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTPS_HOST} !^www.example.com$ [NC,OR]
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]
If you want to do it from the tomcat server follow the below steps
In a standalone Apache Tomcat (8.5.x) HTTP Server, how can configure it so if a user types www.domain.com, they will be automatically forwarded to https(www.domain.com) site.
The 2 step method of including the following in your [Tomcat_base]/conf/web.xml before the closing tag
step 1:
<security-constraint>
<web-resource-collection>
<web-resource-name>HTTPSOnly</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
and setting the [Tomcat_base]/conf/server.xml connector settings:
step 2:
<Connector URIEncoding="utf-8" connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="443"/>
<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" SSLEnabled="true">
<SSLHostConfig>
<Certificate certificateKeystoreFile="[keystorelocation]" type="RSA" />
</SSLHostConfig>
</Connector>
Note: If you already did the https configuration and trying to redirect do step 1 only.
Not only can you do this in your .htaccess file, you should be doing this period. You will also want to follow the steps here to get your site listed on the HSTS preload list after you implement this redirect so that any requests to the insecure http version of your website never make it past the user agent. Instead, the user agent checks the requested URI against a baked in list of https only websites and, if the requested URI is on that list, changes the protocol from http to https before transmitting the request to the server. Therefore, the insecure request never makes it out into the wild and never hits the server. Eventually when the internet changes over to https only the HSTS preload list will not be needed. Until then, every site should be using it.
In order to perform the redirect, we need to enable the rewrite engine and then redirect all traffic from the http port 80 to https.
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://yourwebsite.tld/$1 [L,R=301]
I tried all .htaccess configurations I could find on the internet but none worked.
Then, I realized Apache discourages using mod_rewrite.
My solution was to edit apache configuration files under the following folder:
/etc/apache2/sites-enabled
You will have one mandatory file named 000-default.conf and an ssl configuration file named 000-default-le-ssl.conf (if you have installed ssl certificate from letsencrypt/certbot). However, these files can be named differently depending on the file names you provided when setting up the site.
In 000-default.conf, I edited the following inside <VirtualHost *:80> as:
<VirtualHost *:80>
ServerName example.com
Redirect / https://example.com/
</VirtualHost>
In 000-default-le-ssl.conf, I edited the following inside <VirtualHost *:80> as:
<VirtualHost *:80>
ServerName example.com
Redirect / https://example.com/
</VirtualHost>
No other redirection is needed.
Save the file then restart the apache server using sudo service apache2 restart
I was actually trying to get this to work on an EC2 instance without a load balancer since that costs money. I've read everywhere that .htaccess isn't the "right" way to do it. Obviously, it will work, but I was trying to keep things by the book. I was following all of the examples to update the httpd.conf file and adding a lot of unnecessary stuff. It turns out the only line you really need is this:
Redirect permanent / https://www.yourdomain.com
My problem was that originally I had added this in a VirtualHost tag inside of httpd.conf, which is what a lot of posts tell you to do, but it wasn't working. It turns out there was a separate conf file stored in /etc/httpd/conf.d called yourdomain.conf which already had the VirtualHost tag and was overriding my httpd.conf settings. I just added the above line inside of it and voila, it instantly redirected to https. There is no need for the separate VirtualHost for port 443.
It's working now and the VirtualHost tag looks like this:
<VirtualHost *:80>
ServerName yourdomain.com
DocumentRoot /var/www/html
ServerAlias www.yourdomain.com
ErrorLog /var/www/error.log
CustomLog /var/www/requests.log combined
Redirect permanent / https://www.yourdomain.com
</VirtualHost>
Note: I already had TLS setup with a FREE certificate from certbot (Love those guys) and was just trying to redirect regular http calls to the working https site.
If you are using Apache, mod_rewrite is the easiest solution, and has a lot of documentation online how to do that. For example: http://www.askapache.com/htaccess/http-https-rewriterule-redirect.html
A different edge to this problem is when a Load Balancer comes into play.
The situation is as follows:
- Traffic from browser to Load Balancer, and back, is (should be) HTTPS
- Traffic between Load Balancer and actual WebServer is HTTP.
So, all server request variables in PHP or Apache show that the connection is just HTTP. And the HTTP and HTTPS directories on the Server are the same.
The RewriteCondition in the approved answer does not work.
It gives either a loop or it just doesn't work.
Question is: How to get this working on a Load Balancer.
(Or is the Load Balancer configured wrong. Which is what I'm hoping for because then I can move the problem over to the WebHosting company :-) )
If you're using an Amazon Web Services Elastic Load Balancer which accepts https traffic and routes it to your server(s) with http, the correct way to redirect all http traffic to https is described here: https://aws.amazon.com/premiumsupport/knowledge-center/redirect-http-https-elb
Use the X-Forwarded-Proto header (contains http or https) which is always included in http requests from the load balancer, as described here: https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/x-forwarded-headers.html
In the httpd.conf file:
<VirtualHost *:80>
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule .* https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]
</VirtualHost>
Or in your root .htaccess file:
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule .* https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]
Bonus: it will not try to redirect http traffic on your local development machine.
It works for me:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
and for example, http://server/foo?email=someone%40example.com redirects normally without any issues.
The file .htaccess located in the website root folder (for example named public_html).
It is possible to use
RewriteCond %{SERVER_PORT} !^443$ instead RewriteCond %{HTTPS} !on

Redirect www.subdomain.domain.org to domain.org

What I would like, is to redirect www.subdomain.domain.org to domain.org using the same .htaccess in both websites.
I already have the following:
RewriteCond %{HTTP_HOST} !^domain\.org$ [NC]
RewriteRule ^(.*)$ http://domain.org/ [L,R=301]
which redirects everything that is not domain.org to domain.org, though, it is not redirecting when the URL starts with www.
I have tried many other things but it seems like .htaccess cannot detect if the URL starts with www or not.
Thanks in advance.
After a few days, I have have found a fix for this.
It requires you to edit the /etc/apache2/sites-available/subdomain.domain.org.conf And have a new <VirtualHost *:80> (unless you already have one specifically for www.subdomain.domain.org) with inside of it:
ServerName www.subdomain.domain.org
Redirect permanent / http://subdomain.domain.org/
Which will then redirect www.subdomain.org to subdomain.org.
(Apache2 reload may be required, and can help you if you to see if you have any syntax errors)

.htaccess with dynamics subdomains

I tried to make a .htacces to simulate dynamics subdomains.
like his post :
.htaccess: mod-rewrite; subdomain
but it's impossible for me to get the expected result.
i have read several times the doc at : apache
i have no problem with : RewriteCond, RewriteRule, regular expression.
But i have problems with the subdomain.
i have this page : tododiversion.es
and for my example, I want this :
chr.tododiversion.es ==> tododiversion.es/chr/
i put .htaccess in the www folder: www/ .htaccess
and the folder "chr" is in : www/chr/
in the htacces i put :
RewriteEngine On
# host starts with something else
RewriteCond %{HTTP_HOST} ^([^\.]+)\.tododiversion\.es$ [NC]
# rewrite
RewriteRule ^(.*)$ /chr [L]
it doesn't work..
I know that urlrewritting is working because I made a simple test.
I know that RewriteCond is working because I made a simple test.
I was trying on my computer with localhost and 127.0.01 and it didn't work neither.
If someone could give me some advice it should be great!
Chris
The issue could be that apache is not properly configured to handle subdomains. Make sure that you have all subdomains set up to forward to this directory, or the .htaccess will never be executed.
<VirtualHost *:80>
ServerName domain.com
ServerAlias *.domain.com
DocumentRoot /var/www/domain.com
</VirtualHost>
Remember to restart Apache after updating your config files.
For a reference, see How to configure subdomains for Apache2 on Ubuntu?
You need to include $1 in the rewrite rule so that any URL specifics after the domain are passed on.
chr.tododiversion.es/page.html ==> tododiversion.es/chr/page.html
Based on the link you provided, the rewrite rule should be as follows:
# rewrite
RewriteRule ^(.*)$ /%1/$1 [L]

Is there a way to create subdomain like url redirection using .htaccess?

I want to write a .htaccess from which the following action should be done.
I have domain like
www.xyz.com
and am putting many articles on that.
so it wil become
www.xyz.com/article1-tutorial/
www.xyz.com/article2-tutorial/
www.xyz.com/article3-tutorial/
But instead of that i need like this.
www.article1-tutorial.xyz.com/
www.article2-tutorial.xyz.com/
www.article3-tutorial.xyz.com/
Please help to find the solution. I know we cant go for subdomain concept and only the way is redirection. So whats is the solution?
You'll need something like this in your apache.conf:
<VirtualHost *:80 >
ServerName automated_domains
ServerAlias *.xyz.com
VirtualDocumentRoot /home/xyzcom/website/
</VirtualHost>
Then in the PHP file you put in /home/xyzcom/website, you can get the domain that was actually called in the $_SERVER['HTTP_HOST'] variable.
Hope this helps!

You can use apache's mod rewrite like so:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !www.domain.com$ [NC]
RewriteCond %{HTTP_HOST} ^(www.)?([a-z0-9-]+).domain.com [NC]
RewriteRule (.*) %2/$1 [L]
when a user goes to http://article1-tutorial.domain.com/
server internaly rewrites therequest to http://www.domain.com/article1-tutorial
Can you use the reverse proxy engine of apache?
