I'm curious as to how Tumblr's vanity sub-domain works.
I'm not sure if its through an htaccess redirect but how would you rewrite:
myname.mywebsite.com
To:
www.mywebsite.com/profile.php?username=myname
Any pointers is deeply appreciated.
You don't necessarily need to rewrite anything. You can configure a web application instance or website (in IIS, Apache, etc) to respond to all requests, regardless of Host header (i.e. the domain name). The web application can then interrogate the Host header within application code and respond accordingly:
<?php
$domainName = $_SERVER['HTTP_HOST'];
if( $domainName == 'foo.mydomain.com' ) {
// do something special?
} else {
echo $domainName;
}
?>
Also note that the guide on Apache's website ( http://httpd.apache.org/docs/2.0/misc/rewriteguide.html ) states how to perform URI rewriting based on the Host header (see the section on "Virtual User Hosts"):
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.[^.]+\.host\.com$
RewriteRule ^(.+) %{HTTP_HOST}$1 [C]
RewriteRule ^www\.([^.]+)\.host\.com(.*) /home/$1$2

I'd like to use mod_rewrite to show pretty urls in my urls:
Instead of
.../juegos/plants-vs-zombies/?play=jugar
change to
.../juegos/plants-vs-zombies/jugar/
And
.../juegos/ddtank/?play=full
change to
.../juegos/ddtank/full/
I use the file "single.php" with this code:
$url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$parts = parse_url($url);
parse_str($parts['query'], $query);
$parametro = $query['play'];
if ($parametro == 'jugar')
{
include( get_template_directory() . '/single-play.php');
}
else if ($parametro == 'full')
{
include( get_template_directory() . '/single-full.php');
}
And in .htaccess I have this:
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)play=jugar($|&)
RewriteRule ^(.*)/$ /jugar/?&%{QUERY_STRING}
But when I try to get the url with /jugar/ and /full/ at the end of the url, it displays an 404 error.
I don't know what else to do. I hope you can help me.
Sounds pretty straight forward to me:
RewriteEngine on
RewriteRule ^/?juegos/plants-vs-zombies/jugar/?$ /juegos/plants-vs-zombies/?play=1 [END]
For that to work the rewriting module has to be installed and enabled, obviously. The rule will work likewise in the http servers host configuration and in a dynamic configuration file (.htaccess). If you decide to use a dynamic configuration file, then you need to place that in the http hosts document root folder and enable its interpretation using the AllowOverride directive in the host configuration.
If you receive a http status 500 using the above rule ("server internal error") chances are that you operate a very old version of the apache http server. In that case try replacing the [END] flag with the [L] flag.
And a general hint: you should always prefer to place such rules inside the http servers (virtual) host configuration instead of using dynamic configuration files (.htaccess style files). Those files are notoriously error prone, hard to debug and they really slow down the server. They are only supported as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).

Passing Query String Parameters in WordPress URL
I currently have a Geo-redirect set up in my htaccess to redirect user say from Asia who visits example.com to asia.example.com. I am now wondering how to override that redirection so users from asia.example.com can get to example.com through a link on asia.example.com.
Is that possible or do I have to use a client-side redirect and how would I go about setting that up.
And some background info example.com is running Magento and asia.example.com will be a landing page for now.
Thanks
Update: My host says I should install this https://github.com/maxmind/GeoIP2-php on Magento... How would I do that?
Update from comment:
# Redirect multiple countries to a single page
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(VN|SG|CN|MY|JP|KP|KR)$
RewriteRule ^(.*)$ asia.example.com$1 [R,L]
Normally Magento offers a store switcher in the form of a select field, see it working on demo.magentocommerce.com. The theme in use might change how this is displayed, it could be a link or button instead but the principle is the same, a store cookie is written with the store code as it's value. We can test for that directly in .htaccess and avoid GeoIP if present.
# Redirect multiple countries to a single page
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(VN|SG|CN|MY|JP|KP|KR)$
# New cookie condition goes here
# ! means true when it doesn't match
# \b means word boundary
RewriteCond %{HTTP_COOKIE} !\bstore=default\b
RewriteRule ^(.*)$ asia.example.com$1 [R,L]
It is necessary for the cookie to be transmitted on every request or the user might find themselves being redirected later. You may have to set the cookie domain to .example.com (note the leading period) if it misbehaves. You can do this in Magento's admin under System > Configuration > Web > Session Cookie Management. This allows the cookie to be written by asia.example.com and be read by example.com, and vice versa.
If you want to make a link instead of the store switcher then use Mage::getUrl in this way, it will generate an URL with a ___store query parameter:
<?php
$url = Mage::getUrl('', array(
'_store' => 'default',
'_store_to_url' => true
));
?>
<?php echo $this->__('International Store') ?>
I own a domain since long, just masking the names:
http://mydomain.com
Later I started using a subdomain on this domain for some project.
http://subdomain.mydomain.com
Those projects grew and now I have a structure like
http://subdomain.mydomain.com/project1
http://subdomain.mydomain.com/project2
http://subdomain.mydomain.com/project3/subproject1
http://subdomain.mydomain.com/project3/subproject2
http://subdomain.mydomain.com/project3/subproject3
http://subdomain.mydomain.com/project4
....
etc.
now I bought a new domain (shortdomain.com) where I plan not to move anything but everything should be accessible via redirects so everything looks like:
http://shortdomain.com
http://shortdomain.com/project1
http://shortdomain.com/project2
http://shortdomain.com/project3/subproject1
http://shortdomain.com/project3/subproject2
http://shortdomain.com/project3/subproject3
http://shortdomain.com/project4
...
etc.
So basically I need to do two things:
1. if anyone visits my old domain, redirect them the new naming structure. i.e. if someone loads http://subdomain.mydomain.com/project2 they should be redirected to http://shortdomain.com/project2
when a user loads/redirected to http://shortdomain.com/project2 this should actually load the content present at http://subdomain.mydomain.com/project2
So I will not manually migrate projects,codes and GBs of other data. I think this might be acievable by smart redirection only.
Just FYI:
1. I have full DNS control of both the domains
2. I am hosted on hostgator
3. I use cloudflare on the first domain and would like to continue using it
I think this might be acievable by smart redirection only.
No, redirection changes what's in the browser's location bar. If you redirect to shortdomain.com then the request will get sent to shortdomain.com, and have nothing to do with subdomain.mydomain.com anymore. If you redirect back to subdomain.mydomain.com, then the location bar in the browser will change as well.
What you really want to do is point shortdomain.com to the same server and document root that subdomain.mydomain.com is on. Then use this to redirect (either in htaccess file or server config):
RewriteEngine On
RewriteCond %{HTTP_HOST} ^subdomain\.mydomain\.com$ [NC]
RewriteRule ^(.*)$ http://shortdomain.com/$1 [L,R=301]
If, for whatever absurd reason you can't point the shortdomain.com DNS to the same webserver that serves subdomain.mydomain.com, or can't setup that webserver to accept requests for the shortdomain.com host, you need to setup a proxy server. And it'll work something like this:
2 Webservers, server A (hosts subdomain.domain.com) and server B (hosts shortdomain.com)
Someone requests http://subdomain.mydomain.com/project3/subproject1
server A gets the request and redirects the browser to http://shortdomain.com/project3/subproject1
browser's location bar changes to new location
server B gets the request and reverse proxies the request back to server A
server A gets the request again but must recognize that it is a proxy and then serve the page instead of redirecting
As you can see, this is a horrendously ineffecient solution. It's also a high possibility that your hosting service won't allow you to setup proxy servers.
I have full DNS control of both the domains
With full control I assume you can enable mod_proxy as well on Apache web-server of shortdomain.com. Once that is done set it all up this way.
On subdomain.mydomain.com enable mod_rewrite and place this rule in Apache config OR DOCUMENT_ROOT/.htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^subdomain\.mydomain\.com$ [NC]
RewriteRule ^ http://shortdomain.com%{REQUEST_URI} [L,R=301]
On shortdomain.com enable mod_proxy, mod_rewrite and place this rule in Apache config OR DOCUMENT_ROOT/.htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^shortdomain\.com$ [NC]
RewriteRule ^ http://subdomain.mydomain.com%{REQUEST_URI} [L,P]
I have a domain www.domain.com with this kind of url
www.domain.com/my-italian-page.html (already rewritten by others htaccess rules)
I'd like to create a fake multilanguage url like
www.domain.com/my-english-page.html
The user will see in the address bar the rewritter url www.domain.com/my-english-page.html but the content that I'd like to show is the original www.domain.com/my-italian-page.html .
I'm on a shared server so I can't use apache vhost rule so I have to find a solution via htaccess.
Someone could help me to find the right way?
Thanks
So you want english URLs pointing to italian content? Hope your php script that generates these rewrite rules does the translating. But you'd do this for each one of your pages:
RewriteRule ^/?english-page.html$ /italian-page.html [L]
for each one of your pages.
Generally you want to keep the code executed in the web server as small as possible, so having a rewrite rule for each page is not usually a good idea. I suggest to implement this the way most CMS work when SEO URLs are enabled:
Rewrite any url (mydomain/anytext.html [actually you should not use the .html extension either]) to a script (eg. mydomain.tld/translate.php)
Use content of $_SERVER['PATH_INFO'] (should contain anytext.html) to display the correct page
Set correct HTTP response code if page does not exist: http_response_code(...) (see end of this answer for a function on php5 below 5.4: PHP: How to send HTTP response code?)
Sample .htaccess (actually originally "stolen" and severely modified from a typo3 setup)
RewriteEngine On
# Uncomment and modify line below if your script is not in web-root
#RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule (.*) translate.php$1 [L]
Very basic pseudo-code-like (not tested, there may be syntax errors) example:
<?php
// using a database? you have to escape the string
$db = setup_db();
$page = db->escape_string(basename($_SERVER['PATH_INFO']));
$page = my_translate_query($page);
// no database? do something like this.
$trans = array( 'english' => 'italian', 'italian' => 'italian' );
$page = 'default-name-or-empty-string';
if(isset($_SERVER['PATH_INFO'])) {
if(isset($trans[basename($_SERVER['PATH_INFO'])])) {
$page = $trans[$trans[basename($_SERVER['PATH_INFO'])]];
}
else {
http_response_code(404);
exit();
}
}
// need to redirect to another script? use this (causes reload in browser)
header("Location: otherscript.php/$page");
// you could also include it (no reload), try something like this
$_SERVER['PATH_INFO'] = '/'.$page;
// you *may* have to modify other variables like $_SERVER['PHP_SELF']
// to point to the other script
include('otherscript.php');
?>
I saw in your answer that you have another script - dispatcher.php - which you seem reluctant to modify. I modified my response accordingly, but please keep in mind that by far the easiest way would be to just modify the existing script to handle any English paths itself.
I have a site which has pages like this:
blabla.com/page/whatever
blabla.com/category/whatever
blabla.com/about
...
How can I redirect each of these to a new domain, like:
blabla.net/page/whatever
blabla.net/category/whatever
blabla.net/about
...
?
Using .htaccess
Use the Redirect directive:
Redirect / http://blabla.net/
This directive automatically preserves anything specified after the /.
It might take a bit of fiddling, but the basic idea should work here:
RewriteEngine on
RewriteRule ^(.+)$ http://blabla.net/$1 [R,NC]
You need to have mod_rewrite installed in Apache.
This says "match all URLs on this site, and redirect them to http://blabla.net/the same URL. The [R] means to actually send a redirect request to the client (so the client will make the request to the new server), rather than just serving up the page but keeping the browser URL the same. You can take the R out if you just want to serve the page but keep the old URL.
Or if you use nginx (like we at http://applehub.us, http://crazyfootball.net etc)
location ~ ^/.*_sitemap([\d]+)?.(xml|xml.gz)$ {
rewrite /(.*) /$1 break;
proxy_pass http://yourupstrem;
}
