Subject Re: [users@httpd] Reverse proxy cache control problems
Date Sun, 09 Dec 2007 21:18:09 GMT

After reading a bit more on what RFC 2616 says about Cache-control I 
figured out it was apparently the
Cache-Control: max-age=0

header the browser was sending that made mod_cache not use the cached 
copy even though the server was returning
Cache-Control: max-age=3600

After switching the line to
Cache-Control = s-maxage=3600

caching seems to be working as planned.

Another option would've been to use the following configuration directive:
CacheIgnoreCacheControl On
