htaccess - conditional rewrite and expire

.htaccess, apache, cache-control, mod-expires, url-rewriting

Solution

How about something like this?

RewriteEngine on
RewriteRule ^static/([^/]+\.(png|jpg|css|js))x?/\d{8,15}$ /static/$1 [NC,L]

<FilesMatch "\.(png|jpg|css|js)$">
    <IfModule mod_expires.c>
        ExpiresActive On
    </IfModule>
    <IfModule mod_headers.c>
        ExpiresDefault "access plus 10 years"
    </IfModule>
</FilesMatch>

Problem

Hey there! I have a folder `/static` in my Apache 2.x server webroot. If a request matches ``` /static/<somename like [\S-_]+>.(png|jpg|css|js)/\d{8,15} ``` for example ``` /static/bg.jpg/1335455634 ``` I want two things: - url shall be rewritten to `/static/bg.jpg` (getting rid of the timestamp) - it shall become a never-expire ('expires 2030, max-age=290304000, public cache, ...) If the request does not match, the request and it's headers should be as normal, no rewrite. Ideally, any request outside /static/* should not be affected (though «coincidental trailing timetamps» should be rare...) I have nothing but trouble with FilesMatch / RewriteCond, so I rather not post my poor attempts... (Rewrite in genereal is enabled on my machine, and I do possess the rights to send cache-related headers) Dankeschön!
