Mod_Rewrite Exclude a url (URI Exception) - mod-rewrite

I am using this mod-rewrite rule to redirect the just the homepage of my site to the /it/ sub-directory on the same site.
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RedirectMatch 301 ^/$ http://www.example.com/it/
However, I want to exempt this url from being redirected
http://www.example.com/?act=25
How can I write an exempt condition to do this?


Found a solution
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteCond %{QUERY_STRING} !^act=(.*)$ [NC]
RewriteRule ^$ http://www.example.com/it/
Oh, and RewriteCond does not work with RedirectMatch in case you didn't know (I didn't and wasted hrs because of it)

why is this mod_rewrite rule not working?

I have this rule:
RewriteEngine On
RewriteRule ^([^/]*)$ /?id=$1 [L]
And it's supposed to make http://www.somedomain.com/?id=3123123 accessible as http://www.somedomain.com/3123123 but I then get a 500 error. Why is that?

I ended up using this:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index.php
RewriteRule ^(.*)$ /index.php?id=$1 [L]

mod_rewrite: don't rewrite any subdomains

Is there a way to exempt any requests to a subdomain in mod_rewrite? Right now, I have a one-page app that's redirecting everything to index.html.
<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !index
RewriteRule (.*) index.html [L]
</IfModule>
But I want to make sure that calls to subdomain.mydomain.com are permanently exempt from being rewritten.

You can use a condition on the subdomain and the - substitution to stop the rewriting. From http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewriterule
There is a special substitution string named '-' which means: NO
substitution! This is useful in providing rewriting rules which only
match URLs but do not substitute anything for them.
Try
RewriteEngine On
RewriteCond %{HTTP_HOST} ^subdomain\.mydomain\.com$ [NC]
RewriteRule .* - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !index
RewriteRule (.*) index.html [L]

Using mod_rewrite with multiple Drupal installations

I have a website with Drupal installed in a subfolder /drupal. This instance needs to handle all URLs for the site, which it does successfully with the rules below:
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} !^131.216.164.200:10011$ [NC]
RewriteRule .* http://131.216.164.200:10011/ [L,R=301]
RewriteRule ^$ drupal/index.php [L]
RewriteCond %{DOCUMENT_ROOT}/drupal%{REQUEST_URI} -f
RewriteRule .* drupal/$0 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* drupal/index.php?q=$0 [QSA]
However, I now need to add another Drupal folder, /otherdrupal, which will handle only URLs beginning with /something1 or /something2. What I've tried is modifying the rules to this:
RewriteCond %{HTTP_HOST} !^131.216.164.200:10011$ [NC]
RewriteRule .* http://131.216.164.200:10011/ [L,R=301]
RewriteRule ^(something1|something2)$ otherdrupal/index.php [L]
RewriteRule ^$ drupal/index.php [L]
RewriteCond %{DOCUMENT_ROOT}/drupal%{REQUEST_URI} -f
RewriteRule .* drupal/$0 [L]
RewriteCond %{DOCUMENT_ROOT}/otherdrupal%{REQUEST_URI} -f
RewriteRule .* otherdrupal/$0 [L]
But mod_rewrite is not gonna make it that easy...
(P.S. I'm aware of Drupal's multi-site feature, but assume that the second Drupal instance may be any web application that handles URLs the same way as Drupal does, e.g. with a q URL parameter.)

I figured it out. My working .htaccess file:
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} !^131.216.164.200:10011$ [NC]
RewriteRule .* http://131.216.164.200:10011/ [L,R=301]
RewriteRule ^$ drupal/index.php [L]
RewriteCond %{REQUEST_URI} ^(/something1|/something2)
RewriteRule .* otherdrupal/index.php?r=$1 [L,QSA]
RewriteCond %{DOCUMENT_ROOT}/drupal%{REQUEST_URI} -f
RewriteRule .* drupal/$0 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* drupal/index.php?q=$0 [QSA]

Strange behavior RewriteCond on Apache 2.2

working .htaccess config:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} ^thumbs/(.*)$
RewriteRule ^(.+)$ /index.php [L,QSA]
All 404 queries to /thumbs/ folder not must be catched by /index.php script. Why top .htaccess config work and bottom config not work?
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} !^/thumbs/(.*)$
RewriteRule ^(.+)$ /index.php [L,QSA]
Apache 2.2.9, Debian

REQUEST_URI contains the requested URI path and does always start with a slash.
So the pattern ^thumbs/(.*)$ does never match as it’s missing the leading /. But the other condition, !^/thumbs/(.*)$, should match every request that’s URI path does not start with /thumbs/.

I think it's because the first slash in
RewriteCond %{REQUEST_URI} !^/thumbs/(.*)$

combining force-www with clean urls

I have this mod-rewrite in my htacces which enables some clean urls;
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
### LANGUAGE REDIRECT RULES start
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(en|nl)-?()?\/(.*\/?)$ index.php?language=$1&region=$2&symphony-page=$3&%{QUERY_STRING} [L]
### LANGUAGE REDIRECT RULES end
### FRONTEND REWRITE - Will ignore files and folders
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*\/?)$ ./index.php?symphony-page=$1&%{QUERY_STRING} [L]
</IfModule>
Now I would like to also force www, so I extended the code:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
RewriteBase /
### LANGUAGE REDIRECT RULES start
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(en|nl)-?()?\/(.*\/?)$ index.php?language=$1&region=$2&symphony-page=$3&%{QUERY_STRING} [L]
### LANGUAGE REDIRECT RULES end
### FRONTEND REWRITE - Will ignore files and folders
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*\/?)$ ./index.php?symphony-page=$1&%{QUERY_STRING} [L]
</IfModule>
However this results in none of my pages being found.
FYI A language redirect adds country-code parameters to the url on load.
How do I get these rules to play along?

You're probably missing the query string:
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [QSA,L,R=301]
You can also use the QSA flag in your other rules, e.g.:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*\/?)$ ./index.php?symphony-page=$1 [L,QSA,B]
I also added B because you're using the backreference in a query string, so it needs to be escaped.
See the documentation.
