To answer the question in the subject line, set the LogLevel to debug>>>and look in the error log. That should enable you to determine whether >>>a particular document is cached, and if it is not, determine the reason >>>for that.>>>

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:>>>

Date: Sun, 21 Nov 2004 04:34:49 GMT>>>Server: thttpd/2.25b 29dec2003>>>Content­-Type: text/html; charset=iso-8859-1>­>>Last-Modified: Fri, 19 Nov 2004 21:26:26 GMT>>>Accept-Ranges­: bytes>>>Content-Len­gth: 35484>>>Cache-Contr­ol: max-age=43200>>>Exp­ires: Sun, 21 Nov 2004 16:34:49 GMT>>>

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...>>>
