The problem I am facing is related to CakePHP and I will explain it in that context but it really is a mod_rewrite issue:
In CakePHP, all requests are routed into the /app/webroot directory. In that directory, I have another directory called assets in which all the user-uploaded files are stored. I now want to be able to serve thumbnails for every image in that folder, and I want to auto-generate and then cache them on the first request.
To do that, I have a .htaccess file in the assets directory, which is supposed to route all requests that start with thumbs/ to a PHPThumb script. Now I could simply put said script into the assets directory and everything would work fine. But:
- I want to avoid file bloat (as there can be multiple resolution thumbnails and so on) and would therefore much rather store those thumbnails in the
/app/tmpdirectory, - The whole thing is part of a CakePHP plugin I am developing, so it would be neat if the script could stay in the Plugin's folder.
What I have tried (inside the /app/webroot/assets directory):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^thumbs\/([^\/]*)\/(.*)$ ../../Plugin/MyPlugin/Lib/thumbnail.php?size=$1&path=$2 [QSA,L,S=2]
Now this doesn't work. The problem are the .htaccess files in /app and /app/webroot which route everything to /app/webroot/index.php (or any physical file in webroot). The S flag only seems to apply to rules in the same file.
I obviously could change those files to allow thumbnail.php but as I said, its part of a Plugin and I would prefer to keep it as configuration-less as possible.
So my question: Is there a way to bypass/disable any other rewrite rules after the one in /app/webroot/assets/.htaccess was applied?
