问题
For the sake of formality, I want to trim my asset URIs so that file extensions are omitted.
For example, if I request /resources/stylesheets/common, Apache will return /resources/stylesheets/common.css. At the moment, I'm using the following rewrite to get this to work:
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI}.css -f
RewriteRule ^ /%{REQUEST_URI}.css [L]
This works, as it should. However, I need to also do this for other resources, like images and scripts. For simplicity, I would like to avoid repeating this approach for every type of resource.
Question: What method can I use to achieve this in one rule? I'm thinking something along these lines (though this will not work, and I can see why - perhaps Apache doesn't like guess-work):
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI}.(css|js|png) -f
RewriteRule ^ /%{REQUEST_URI}.%1 [L]
