Question

I’m setting cache control headers for files. I want to set max-age=86400 for all .css and .js, and max-age=3600 for all others.

<FilesMatch "\.(css|js)$">
    Header append Cache-Control max-age=86400
</FilesMatch>

<FilesMatch "???">
    Header append Cache-Control max-age=3600
</FilesMatch>

I can’t figure out what regex I should write to invert \.(css|js)$ match. Or maybe there is some other way to do this?

UPDATE. Based on this question answer I’ve found solution that works:

<FilesMatch "(?<!\.css|\.js)$">
    Header append Cache-Control max-age=3600
</FilesMatch>

Unfortunatelly can’t find a way to leave dot \. outside of brackets. But still this solution fine for me.

As a side note, all other files include ones with not filename at all, like http://example.com/.
