The 2.2 docs state that ExpiresDefault can be placed in server config, virtual host, directory, and .htaccess. It doesn't mention Location.
I have a mod_perl server, and I'd like most, or all, of the non-dynamic content (jpg, css, js, etc.) to expire "infrequently". But I want all mod_perl generated pages to expire "now".
My configuration appears to be working, but I want to make sure I'm not missing something, since it's undocumented.
ExpiresActive on
ExpiresDefault "access plus 1 month"
<LocationMatch ^/app/.*>
ExpiresDefault "now"
</LocationMatch>
