 * Proxy runs apache with mod_proxy. I have my VirtualHosts identified and SiteA
   is proxied to ServerA, SiteB to ServerB, etc. Reverse proxy has been working 
   without issue for years. In trying to make use of browser caching I’m running
   into a roadblock. I’ve pieced together the various solutions I’ve been able to
   find but it’s still not working. On Proxy I have added the following in httpd.
   conf to try and enable browser caching at this layer:
 * > <LocationMatch .*\.nocache\..*>
   >  ExpiresActive On ExpiresDefault “access” </
   > LocationMatch>
   > <LocationMatch .*\.cache\..*>
   >  ExpiresActive On ExpiresDefault “now plus 1 
   > year” </LocationMatch>
 * Previous to that I tried the following with no success:
 * > <Files *.nocache.*>
   >  ExpiresActive On ExpiresDefault “access” </Files>
   > <Files *.cache.*>
   >  ExpiresActive On ExpiresDefault “now plus 1 year” </Files
   > >
 * On ServerA I have the following in /var/www/html/.htaccess:
 * > ## EXPIRES CACHING ##
   >  <IfModule mod_expires.c> ExpiresActive On ExpiresByType
   > image/jpg “access plus 1 year” ExpiresByType image/jpeg “access plus 1 year”
   > ExpiresByType image/gif “access plus 1 year” ExpiresByType image/png “access
   > plus 1 year” ExpiresByType text/css “access plus 1 month” ExpiresByType application/
   > pdf “access plus 1 month” ExpiresByType text/x-javascript “access plus 1 month”
   > ExpiresByType application/x-shockwave-flash “access plus 1 month” ExpiresByType
   > image/x-icon “access plus 1 year” ExpiresDefault “access plus 2 days” </IfModule
   > > ## EXPIRES CACHING ##
 * To the best of my knowledge Proxy has the correct configurations in httpd.conf
   to permit browser caching as does the .htaccess file on ServerA where SiteA lives.
   Testing SiteA with various web tools reports that browser caching is not enabled.
   I am hoping fervently that someone has experience with this sort of setup and
   can help point me in the right direction. Thank you in advance!

 * I slapped up a quick test page in /var/www/test on the server I’m referencing
   above as Proxy. I added the VirtualHost entry for it and then added the following
   to /var/www/test/.htaccess:
 * > ## EXPIRES CACHING ##
   >  <IfModule mod_expires.c> ExpiresActive On ExpiresByType
   > image/jpg “access plus 1 year” ExpiresByType image/jpeg “access plus 1 year”
   > ExpiresByType image/gif “access plus 1 year” ExpiresByType image/png “access
   > plus 1 year” ExpiresByType text/css “access plus 1 month” ExpiresByType application/
   > pdf “access plus 1 month” ExpiresByType text/x-javascript “access plus 1 month”
   > ExpiresByType application/x-shockwave-flash “access plus 1 month” ExpiresByType
   > image/x-icon “access plus 1 year” ExpiresDefault “access plus 2 days” </IfModule
   > > ## EXPIRES CACHING ##
 * Pingdom’s web tool says browser caching is enabled on this test page. I don’t
   know if this is helpful or not in figuring out where the problem is.

 * I just tried something I didn’t think to try previously and have resolved this
   issue. The <IfModule mod_expires.c> block actually goes INSIDE the <VirtualHost
   > block. I’m good to go. Hopefully this helps someone else someday!
