[users@httpd] mod_cache: how to determine its running

[Sean T Allen <se...@usaherbals.com>]

Basics:

Server version: Apache/2.0.52

Compiled in modules:
  core.c
  mod_access.c
  mod_auth.c
  mod_cache.c
  mod_disk_cache.c
  mod_mem_cache.c
  mod_log_config.c
  mod_env.c
  mod_setenvif.c
  mod_proxy.c
  proxy_connect.c
  proxy_ftp.c
  proxy_http.c
  mod_ssl.c
  prefork.c
  http_core.c
  mod_mime.c
  mod_status.c
  mod_autoindex.c
  mod_dir.c
  mod_imap.c
  mod_actions.c
  mod_alias.c
  mod_rewrite.c
  mod_so.c

And lastly issue...

I am reverse proxying to an httpd server instance running on 127.0.0.1:8081
Have a mem_cache setup that doesnt seem to be working....

Here are some snippets:

CacheEnable mem /
CacheRoot /cache/toppik
CacheSize 5000000
CacheGcInterval 1
CacheLastModifiedFactor 0.1
CacheDefaultExpire 3600
CacheMaxExpire 43200
CacheForceCompletion 60
#CacheIgnoreCacheControl On
CacheIgnoreNoLastMod On
MCacheMaxObjectCount 10000
MCacheMaxObjectSize 12800000
MCacheMinObjectSize 0
MCacheRemovalAlgorithm LRU
MCacheSize 100000

There are some disk cache related things in there as I was playing 
around with it during test.

and the mod-rewrite stuff that proceeds the cache entries in the config file

RewriteEngine On

Standard response header example:

Some where o where do I have this misconfigured?
Order that module compiled in?
Something esoteric in the setup?
Freaky rewrite rule getting in the way?

Your help greatly appreciated...
