Htaccess rewrite to file located up one level

.htaccessapache-2.2apache-2.4mod-rewriterewrite

I have an htaccess in a subdomain with the following rule:

RewriteEngine On
RewriteBase /
RewriteRule ^feed([0-9]+)$ ../image.php?id=$1 [L]

So basically I want to redirect requests from feed which is located in a subdomain to image.php file which is located in the main domain (just one directory above). Using ../ doesn't seem to work like in PHP.

So how can I rewrite to file in the parent directory?

By the sounds of it, you are already in the document root of your subdomain, which is probably defined in its own virtual host (which happens to point to a subdirectory off the main domains document root).

Unfortunately, you can't internally rewrite above/outside the document root using mod_rewrite in .htaccess. In .htaccess the RewriteRule substitution takes a URL-path only, not a filesystem path. However, you can do this if you are using mod_rewrite directly in the server config. In the server config you can specify a filesystem path as the substitution (you would need to explicitly include the full path, you can't use a relative path like ../image.php).

Alternatively, in .htaccess you might be able to proxy the request from your subdomain to the maindomain using mod_proxy with mod_rewrite. However, this might still require some server configuration. For example:

RewriteRule ^feed([0-9]+)$ http://maindomain.com/image.php?id=$1 [P]

Debian – Rewrite rule for multiple subdomains issue

Okay, so i made some tests about your case, and here is the working result (i don't think the current RewriteRules , you are using at this time are correct - these showed above).

So here is my tested solution. Example 1 shows rewriting of fisrt level subdomain (eg. subdomain.domain.com), and example 2 shows rewriting second level subdomains (eg. subdomain.subdomain.domain.com).

Here are the examples: Example 1:

1. RewriteEngine On
2. RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com
3. RewriteCond /var/www/html/%1 -d
4. RewriteRule ^(.*) /%1/$1 [L]

- Enable rewrite engine
- catch the 1st level subdomain
- check if the directory (the name of the subdomain) exists
- rewrite the requested file to the directory (the given example uses relative paths)

Example 2:

1. RewriteEngine On
2. RewriteCond %{HTTP_HOST} ^([^\.]+)\.([^\.]+)\.domain\.com
3. RewriteCond /var/www/html/%1/%2 -d
4. RewriteRule ^(.*) /%1/%2/$1 [L]

- Enable rewrite engine
- catch the 1st/2nd level subdomains
- check if the directory (the name of the subdomains) exists
- rewrite the requested file to the directory (the given example uses relative paths)

So here is the result from the given examples above:

Ex. 1 - Hit url test.domain.com/index.php --> redirects to --> /var/www/html/test/index.php

Ex. 2 - Hit url 1.2.domain.com/index.php --> redirects to --> /var/www/html/1/2/index.php

I assume, that the virtualhost is configured with document root of - /var/www/html

Apache – Adding a Rule to htaccess Subdomain Rewrite

Haven't tested it, but try something along these lines (you might need to tweak it):

RewriteCond %{HTTP_HOST} ^domain\.com(:80)?$ [NC]
RewriteRule ^(.*)(?:index.php)?$ http://www.domain.com/$1 [R=permanent,L]

Put the code after RewriteEngine On (i.e. before your first RewriteCond). Note that it's going to remove all index.php endings (i.e. domain.com/a/b/c/index.php will become www.domain.com/a/b/c/. Taken from here:

I suggest you do some reading on mod_rewrite, such as:

if you are going to need it every second day - pays off... :)
