Htaccess filesMatch exclusion

.htaccessapache-2.2http-headersregex

I have the following directive in my htaccess

<filesMatch "\.(gif|jpe?g|png|js|css|swf|php|ico|txt|pdf|xml|html?)$">
    FileETag None
    <ifModule mod_headers.c>
        Header unset ETag
        Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
        Header set Pragma "no-cache"
        Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
    </ifModule>
</filesMatch>

I copied that regex from someplace in Web months ago. It should add those headers to any HTTP Response that does NOT have those extensions.

But it's not working, it's adding them to any Response.

I also need to create another directive to add Header set Cache-Control "max-age=3600, public" to Responses of files that DOES have them.

Could anybody help me make proper fileMatch regexes?

You've got a few capitalization errors in your config:

<filesMatch "\.(gif|jpe?g|png|js|css|swf|php|ico|txt|pdf|xml|html?)$">
 ^
 should be <FilesMatch ...

    <ifModule mod_headers.c>
     ^
     should be <IfModule...

    </ifModule>
      ^ 
      should be </IfModule>
</filesMatch>
  ^
  should be </FilesMatch>

Also, if you've got VirtualHosts, you need to make sure that you've got AllowOverride correctly configured

Apache Caching – Apache Caching with mod_headers and mod_expires

You need to use the

ExpiresActive On

directive wherever you want to apply Expires headers, for example

<Location / >    
   ExpiresActive On
   ExpiresByType image/png "access plus 7 days"    
   ExpiresByType image/jpg "access plus 7 days"    
   ExpiresByType image/gif "access plus 7 days"

   ExpiresByType text/html "modification plus 5 days"

   <FilesMatch "\.(gif|jpe?g|png)$">        
      Header set Cache-Control "public"    
   </FilesMatch>

   <FilesMatch "\.(html)$">        
      Header set Cache-Control "public"    
   </FilesMatch>

   <FilesMatch "\.(php)$">
      Header set Cache-Control "private"    
   </FilesMatch> 
</Location>

Tomcat – Apache2 – mod_expire and mod_rewrite not working in httpd.conf – serving content from tomcat

Probably the ProxyPass / directive you have in your config routes all requests to the Tomcat backend, bypassing all your mod_rewrite directives. You can try to remove the ProxyPass directive and use RewriteRule with the [P] flag after your other rewrites:

mod_rewrite: P|proxy

For the expire headers the situation is worse — in another similar question a solution was not found.

Option +FollowSymLinks would be needed for using mod_rewrite in .htaccess files; in your case it is not required, because you can put everything in the Apache config. Moving rules from config to .htaccess is pointless and can only make things slower. However, there is an important difference between .htaccess and the Apache config — in .htaccess patterns in RewriteRule are matched against relative filesystem paths (which never start with /), while in the VirtualHost context these patterns are matched against the URL path after the hostname, which always starts with /. Therefore at least one of your rules is incorrect:

RewriteRule ^content/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /content/$1/$2.$4

should be

RewriteRule ^/content/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /content/$1/$2.$4

(note the additional slash in the beginning).
