Re: [users@httpd] mod_cache usage

["Deepa Rangarajan" <deepa_rr@xxxxxxxxxxx>]

Hi,

I am using apache 2.0 as reverse proxy and also for caching.
I am caching some images that reside on another server.

Here is a snippet of my httpd.conf :

  CacheEnable disk /abc
  CacheEnable disk /xyz

  CacheRoot "/var/cache/mod_proxy"
  CacheSize 100000
  CacheIgnoreCacheControl On
  CacheIgnoreNoLastMod On
  CacheDefaultExpire 3600
  CacheMaxExpire 3600

I assume that since CacheIgnoreCacheControl On and  CacheIgnoreNoLastMod On 
, even if the HTTP headers not set, i would be able to cache the image in 
the specified URI and this would cache it for an hour before checking for 
any modification.

 However I find that every time I load the page, the image gets loaded 
freshly - seen in the form of GET requests in the actual server.
 At times, I find that it loads from cache, esp. after a few minutes have 
lapsed since the file has been changed.

 How do I ensure that the caching acts according to what I have specifiied. 
If I have not made myself clear pls. let me know..

Thks,
-Deepa
