mod rewrite Rule for Image + String to Imagefolder Rewrite

I have got some images on my server, which were always generated on the fly and requested right here: http://www.mydomain.com/en/images.png?domain=test.com

They are now cached in http://www.mydomain.com/images/test.com.png

I tried the following rule in my htacce开发者_如何学运维ss, but it doesn't work:

RewriteRule ^(en|de)?/images.png\?domain=(.*) /images/$2.png [QSA,L]

Any clue what's wrong?

just found the solution:

RewriteCond %{QUERY_STRING} ^domain=(.*)$ ^ this line was missing to catch the Query String RewriteRule ^(en|de)?/images.png$ /rating-images/%1.png [QSA]

At first glance, you probably need to escape the question mark that is part of the URL.

RewriteRule ^(en|de)?/images.png\?domain=(.*) /images/$2.png [QSA,L]

The query string is not part of what you're comparing to implicitly with RewriteRule, you need a RewriteCond to match/capture it to use in your substitution:
