Routing requests
Again, these rules direct all requests to index.php, except specified file types:
RewriteEngine on RewriteBase / RewriteRule !\\.(js|ico|txt|gif|jpg|png|css)$ index.php
Handling file and directory exceptions
These rules (used immediately prior to the RewriteRule above) exclude real files and directories from the rewriting and lets them pass through unaffected:
RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d
You can also simply allow a specified group of files to pass through unaffected by using this line:
RewriteRule ^(foo|bar).* - [L]
In this case, files foo.* and bar.* will be accessed normally.
