mod_rewrite: Check for Custom query string in URL?

Question

I'm trying to use URL rewrite in my new project. But I also need to allow custom query sting in URL.

I just want to know how to write rewrite rule for this URL

http://www.mysite.com/edit/123/?q1=value1&q2=value2

to become this

http://www.mysite.com/index.php?action=edit&id=123&q1=value1&q2=value2

The custom query string should be allow unlimited.

Millions of Thanks...

Simply do your rule as any other rule and add the QSA modifier (Query String Append) at the end.

RewriteEngine On
RewriteRule ^/([A-Za-z0-9]+)/([0-9]+)/$ index.php?action=$1&id=$2 [L,QSA]
