I\'m writing a CMS in PHP, and now I\'m working at the themes feature. I have a .htaccess file:
RewriteEngine ON
RewriteRule ^([a-zA-Z][a-zA-Z0-9]*)$ index.p
Do something like:
RewriteRule ^THEMES - [L]
That means: if the request starts with THEMES, just serve it.
Another possible solution is:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
That means: do not rewrite if the request resolves to an existing file (first line) or directory (second line).
Maybe you should read the documentations, is really well written.
