mod_rewrite with subdomain and url pattern

I want to use the subdomain as a get variable with mod_rewrite AND use some parameter :

eg /page/language/site/counter -> index.php?o=operator&lg=language&s=arg1&c=arg2

How to do that with mod_rewrite?

RewriteEngine On  

RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteCond %{HTTP_HOST} ^([a-zA-Z]{3,6})\.example\.com  
Rewri开发者_C百科teRule ^index/([a-z]{2})/([0-9]{1,2})/([0-9]{1,2})$  http://www.example.com/index.php?o=%1&lg=%2&site=%3&counter=%4 [NC,L] # for index.php
RewriteRule ^export/([a-z]{2})/([0-9]{1,2})/([0-9]{1,2})$  http://www.example.com/export.php?o=%1&lg=%2&site=%3&counter=%4 [NC,L] # for export.php

Any idea?

Thanks in advance


A RewriteCond does only belong to the directly following RewriteRule. So in your case both RewriteCond directives do only belong to the first RewriteRule directive and the second RewriteRule has no associated RewriteCond directives.

You can fix this in your example by merging the two RewriteRules:

RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteCond %{HTTP_HOST} ^([a-zA-Z]{3,6})\.example\.com$
RewriteRule ^(index|export)/([a-z]{2})/([0-9]{1,2})/([0-9]{1,2})$ http://www.example.com/$1.php?o=%1&lg=$2&site=$3&counter=$4 [NC,L]

Also note the usage of $n instead of %n as $n refers to the match of the n-th group of RewriteRule the while %n refers to the match of the n-th group of the last successful RewriteCond.
