I am trying to write rewrite rules to accept a subdomain as well as an optional page on the end of the domain, example:
a.domain.com
a.domain.com/1
Where "a" can be anything and the 1 is a numeric input.
I currently have the following conditions and rules:
RewriteCond %{HTTP_HOST} !www\.
RewriteCond %{HTTP_HOST} (.*)\.domain\.xyz
RewriteRule .* view.php?username=%1 [L]
which works with the subdomain, but cannot find a way to allow the second parameter on the end to work as well.
What rules can I add to make this work?

I have many subdomains on oldsite.example that I want to 301 redirect to newsite.com. However some subdomains should stay at oldsite.example and the redirected subdomains follow no regex-able pattern, making wildcards irrelevant.
I'd like an expression where I can write a list something like sub1,page,boop which would set up redirects for all the following
sub1.oldsite.example -> sub1.newsite.example
page.oldsite.example -> page.newsite.example
beep.oldsite.example -> beep.newsite.example
Here is a rewrite rule that can be used to do this:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(sub1|page|boop)\.oldsite\.example$ [NC]
RewriteRule ^/?(.*)$ https://%1.newsite.example/$1 [R=301,L,QSA]
RewriteEngine on enables rewrite rules and only needs to be used once in .htaccess
RewriteCond specifies a condition that needs to be met before the rewrite rule is activated
%{HTTP_HOST} is the domain name
(sub1|page|boop) your list of subdomains in a capturing group
[NC] - case insensitive
^/?(.*)$ matches every page on those subdomains with a capturing group
https://%1.newsite.example/$1 the new URL with substitutions of the capturing groups from the condition and the rule
[R=301] - 301 permanent redirect
[L] - Last rewrite rule (so that others don't get triggered after this one matches)
[QSA] - Query string append - preserve any parameters on the URL
i have wildcard subdomains sets already and works fine, now i wish have friends url for the content in thats subdomains, the structure of my site is if the user type subdomain.maindomain.com and the .htaccess redirect to
blogs/index.php?user=subdomain
where blogs/index.php receive the param and show the correct content
now i try to make the url function like this
subdomain.maindoamin.com/24/title-of-content
and then .htaccess must result
blogs/index.php?id_content=24&title=title-of-content
i have the next .htaccess
Options +FollowSymLinks
#this force to server the content always without www.
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.(.*)$
RewriteRule ^(.*)$ http://%1/$1 [R=301]
#this is to pass the subdomain like param and show the right content of the user
RewriteCond %{HTTP_HOST} !^www\.misite\.com [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.misite\.com
RewriteRule ^(.*)$ blogs/index.php?url=%1 [QSA,L]
#the next line i can't make work to make nice url
RewriteRule ^/(.*)/(.*)$ blogs/index.php?idP=$1&name=$2 [L]
not working because when i make in index.php
echo $_SERVER['REQUEST_URI'];
don't show idP=24 show /24/title-of-content and i need $_GET(idP)
i really apreciate some light on this stuff i am not expert on htaccess, thanks in advance to everybody.
There are two problems:
The first argument of RewriteRule matches against everything after the slash of the directory .htaccess is in, and before the query string. If .htaccess is in your www-root, and you get the url http://www.example.com/shiny/unicorns.php?are=shiny, you match against shiny/unicorns.php. It will never start with a slash, so ^/ will never match.
Rules are executed in order. If you go to http://sub.example.com/10/unicorns, the second rule will match first and rewrite the request to /blogs/index.php?url=10/unicorns. If you removed the leading slash the third rule would match, but normally you wouldn't want that. You want to have the third rule only match
You want to move the third rule up so it is the second rule. You want to make it more specific to only match with subdomains. You also know the first part contains only numbers, so use that knowledge to prevent blogs/index.php from matching your now second rule. You also need to prevent blogs/index.php from matching the now third rule to prevent it from matching itself. Last but not least I removed [L] from the now second rule, since the third rule will match anyway.
#the next line i can't make work to make nice url
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^([0-9]+)/([^/]+)$ blogs/index.php?idP=$1&name=$2
#this is to pass the subdomain like param and show the right content of the user
RewriteCond %{HTTP_HOST} !^www\.misite\.com [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.misite\.com
RewriteCond %{REQUEST_URI} !/blogs/index\.php
RewriteRule ^ blogs/index.php?url=%1 [QSA,L]
I need to write an anti-hotlink command for my .htaccess file but it can not be specific to any domain name in particular. Here's what I found on another sites so far but I'm not sure exactly why it doesn't work, can anyone spot the problem?
# Stop hotlinking.
#------------------------------
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^https?://([^/]+)/ [NC]
# Note the # is just used as a boundary. It could be any character that isn't used in domain-names.
RewriteCond %1#%{HTTP_HOST} !^(.+)#\1$
RewriteRule \.(bmp|gif|jpe?g|png|swf)$ - [F,L,NC]
Try this.
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^https?://(www\.)?([^/]+)/.*$ [NC]
RewriteCond %2#%{HTTP_HOST} !^(.+)#(www\.)?\1$ [NC]
RewriteRule \.(bmp|gif|jpe?g|png|swf)$ - [F,L,NC]
Would even work when only one of the referrer or target url has a leading www.
EDIT : (how does this % thing work?)
%n references the n(th) bracket's matched content from the last matched rewrite condition.
So, in this case
%1 = either www. OR "" blank (because it's optional; used ()? to do that)
%2 = yourdomain.com (without www always)
So, now the rewrite condition actually tries to match
yourdomain.com#stealer.com OR yourdomain.com#www.stealer.com
with ^(.+)#(www\.)?\1$ which means (.+)# anything and everything before # followed by www. (but again optional); followed by \1 the first bracket's matched content (within this regex; not the rewrite condition) i.e. the exact same thing before #.
So, stealer.com would fail the regex while yourdomain.com would pass. But, since we've negated the rule with a !; stealer.com passes the condition and hence the hot-link stopper rule is applied.
Currently what is happening is people are accessing old URLs from google like icpaweb.com/site/pages/about-us/ and being sent to their corresponding urls on icpaweb.org : icpaweb.org/site/pages/about-us.
What I want is to send people from: icpaweb.com/site/pages/about-us to icpaweb.org/ without any of the succeeding url segments.
How do I do this?
If you have to use an .htaccess file, you can use mod_rewrite:
RewriteEngine On
RewriteCond %{HTTP_HOST} icpaweb.com$ [NC]
RewriteRule .* http://icpaweb.org/ [R=301,L]
That will 301 redirect all requests for icpaweb.com to the index root of icpaweb.org. If you don't want 301, it can just be R.
You'll need to replace or turn off whatever mechanism is doing your redirecting now, they may not be compatible.
Use an url rewrite rule.
2 steps:
Write a RewriteCond so that the following rewrite rule only apply for url with host being icpaweb.com like RewriteCond %{HTTP_HOST} icpaweb.com$ [NC] The [NC] is for case insensitive match
Write a rewrite rule that convert all input to what you want like RewriteRule ^.*$ http://icpaweb.org/ [L]The [L] is to stop the rewriting to this rule if rule executed.
We've just finished a major re-structuring our website and I'm trying to write a set of redirect rules of varying specificity. The redirects are half working:
They correctly re-route old URLs
They incorrectly also allow and re-route URLs that include text not specified in the
ReWriteCond statements (when instead I would expect to see a "Not Found" error message displayed in the browser.)
Statements in the .htaccess file (located in the root of the web site) include:
RewriteBase /
RewriteCond %{REQUEST_URI} /company/company-history.html
RewriteRule (.*)$ http://www.technofrolics.com/about/index.html
RewriteCond %{REQUEST_URI} /press
RewriteRule (.*)$ http://www.technofrolics.com/gallery/index.html
The above correctly executes the desired redirect
but also works when I enter the following after the domain name:
/youcanenteranytext/hereatall/anditstillworks/press
In other words, any text following the domain and preceding the conditional string seems to be allowed/ignored. Any advise on how to restrict the condition or rewrite rule to prevent this would be much appreciated!
Thanks, Margarita
You need to including bounds in your regular expressions when you try to match against %{REQUEST_URI}, the ^ indicates the beginning of the match.
RewriteCond %{REQUEST_URI} ^/company/company-history\.html
Will make it so requests for /garbage/stuff/comapny/company-history.html won't match. And likewise:
RewriteCond %{REQUEST_URI} ^/press
Will make it so requests for /youcanenteranytext/hereatall/anditstillworks/press won't match. You can additionally employ the $ in your regular expression to indicate the end of the match, so something like this:
RewriteCond %{REQUEST_URI} ^/press$
Will ONLY match requests for /press and not /something/press or /press/somethingelse or /press/.
