.htaccess conditional rewrite

Question

Hi guys,

I'm trying to create an conditional Rewrite Rule using an .htaccess file and Apache.

Basically what I need is that the Apache would check if the requested file exists in a sub folder, case in which Apache would serve this existing file, or, if the file does not exist, Apache would load the index.php file.

The folder structure I'm using is:

- /gallery
  - /cache
  - index.php
  - .htaccess

also, the .htaccess I have now is

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.+) - [PT,L]
RewriteRule ^(.*)$ index.php/$1 [L]

however, this works only if the file I'm trying to look for is in the /gallery folder, however I need to look if the file exists in the /cache folder instead.

Does anyone know how to modify this rules in order to achieve that?

Thank you in advance,

Try these rules:

RewriteCond %{REQUEST_URI} ^/(([^/]+/)*)gallery/
RewriteCond %{DOCUMENT_ROOT}%1gallery/cache/$0 -f
RewriteRule ^.+ cache/$0 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^.* index.php/$0 [L]

The first rule checks if the requested path is a path to an existing file in the cache directory. If so, it rewrites the request to that file.
