Squid Caching Issue

Linux and Unix-Like Red Hat
1

Hi frnds

I recently configured Squid 2.5 stable version on my redhat machine.Caches are storing in my disk (/var/spool/squid) but my access.log file always shows tcp_miss for every site i access as well as store.log file shows release on every action.

some of the records of my access.log and store.log below

This may not be wrong; dynamically-generated websites and the like probably won't be cached. Try downloading an image twice to see if the retrieval is cached the second time.

3

Hii

I tried with some static websites and now logs showing TCP_Refresh_HIT or TCP_IMS_HIT but not TCP_HIT on any object.

pls suggest

Try it on something actually static, like an image file, and see what happens.

5

Hii

trying to access image file but Same result (TCP_Miss) and TCP_Refresh_HIT showing Direct access

is anything wrong with Refresh_pattern

pls suggest

I can't see your config file from here, sorry. Could you post it(stripping out comments and blank lines)?
