Using mod_rewrite with multiple Drupal installations - mod-rewrite

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]

Redirection loop URL rewriting

I'm redirecting all my .php extensions to .html, but I'm getting a loop problem.
For example, from:
-mywebsite.com/country/france-php/paris.php
to
-mywebsite.com/country/france-php/paris.html
Here is my .htaccess:
RewriteEngine On
RewriteBase /
RewriteRule (.+)\.php$ $1.html [R=301,L]
RewriteRule (.+)\.html$ $1.php [L]
FallbackResource /index.php
When analyzing with redirection detective I get many redirections to:
-mywebsite.com/country/france-php/paris.html

Do the first redirection based on raw request received:
RewriteCond %{THE_REQUEST} ^GET\ /(.+)\.php
RewriteRule ^ /%1.html [R=301,L]
RewriteRule ^(.+)\.html$ /$1.php [L]
To load index.php as index.html too, you can add the following rewrite at the top:
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{REQUEST_URI} ^(.*)/$
RewriteRule ^ %1/index.php [R=301,L]

You can try your rules this way.
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\ /(.+)\.php
RewriteRule ^ %1.html? [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.+)\.html$ $1.php [L]

Try:
RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} \ /+([^\?\ ]+)\.php([^\?\ ]*)
RewriteRule ^ %1.html%2 [L,R=301]
RewriteCond %{DOUMENT_ROOT}/$1.php -f
RewriteRUle ^(.+)\.html(?:(/.*)|)$ $1.php$2 [L]
The problem is that the rewrite engine loops and your two rules keep overwriting each other. By adding some conditions, you can prevent that.

Mod_Rewrite Exclude a url (URI Exception)

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)

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]

How to write the mod_rewrite rules for these requirements?

I need to make rules for mod_rewrite:
from
http://site.kiev.ua/index.php
http://www.site.kiev.ua/
http://www.site.kiev.ua/index.php
to
http://site.kiev.ua/
from
http://site.kiev.ua/catalog/products/941
to
http://site.kiev.ua/catalog/products/941/
from
http://site.kiev.ua/catalog/products/941/index.php
to
http://site.kiev.ua/catalog/products/941/
941 - it may be any category

RewriteEngine On
RewriteBase /
# www to none www
RewriteCond %{HTTP_HOST} ^www.domain.com [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [L,R=301]
# Remove index.php
RewriteCond %{THE_REQUEST} \ /(.+/)?index\.(html?|php)(\?.*)?\ [NC]
RewriteRule ^(.+/)?index\.(html?|php)$ ./$1 [R=301,L]
# Force trailing slashes.
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule [^/]$ %{REQUEST_URI}/ [R=301,L]
# /file.php to /file/
RewriteCond %{REQUEST_URI} ^(/.*[^/])/?$
RewriteCond %{DOCUMENT_ROOT}%1.php -f
RewriteRule ^([^/]+)/?$ ./$1.php [QSA,L]

Options +FollowSymlinks -Indexes
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.site\.kiev\.ua$ [NC]
RewriteRule ^(.*)$ http://site.kiev.ua/$1 [L,R=301]

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.
