Cache.log shows a lot of TCP_MISS and no TCP_HIT
|
|
|
Hi,
We are evaluating Squid for NT and we are noticing a lot of TCP_MISS and
no TCP_HITs in our logs. We see TCP_IMS_HIT and TCP_REFRESH_MISS too.
I think nothing gets used from the cache.
I've added our configfile (used a script that only shows the lines
without a # in front of it), so the rest is default.
We use version 2.5.STABLE9-NT-CVS
Can anyone tell me what we can do to get TCP_HITs ?
Thanks in advance for any info.

If you are evaluating using browser refresh options,
then that's normal.

You can't , but remote webservers can, by providing cacheable |
objects.
Check with :

Hi,
Tnx for you help.
I checked some sites and that site shows "validated" but anyhow, we are
surfing with a testgroup of 10 persons and we got no TCP_HIT at all in
our logs....very weird.
In the log-directory I see files with today's date so something is
getting in the cache but nothing is getting out?

Post examples from access.log, if possible.

Hi all,
I found the error.
acl QUERY urlpath_regex cgi-bin \?
acl NoCacheDomains dstdomain .checkpoint.com
acl local-servers src 172.20.0.0/16 192.168.100.0/24
no_cache deny QUERY
no_cache deny NoCacheDomains
no_cache deny local-servers
This should not be in your configurationfile if your own network is
172.20.0.0/16 and 192.168.100.0/24. Because the ACL looks to the source
IP's it will never cache requests coming from those ranges and therefore
it cannot cache anything.
I also noticed I had pasted the wrong configfile in my first mail so you
guys couldn't have found the cause of my problem... so lesson learned:
always paste the config you are using. *doh*
One question though: what does TCP_IMS_HIT mean? What is "IMS"?
Kind regards,
Jeroen. |
