[squid-users] RE: TCP_MISS/200 with squid-2.7.STABLE6 Reverse proxy config

Have you tried bumping up the logging level and seeing what the cache.log tells you? http://www.squid-cache.org/Versions/v2/2.7/cfgman/debug_options.html

You could try bumping up the debug level for all components, or you could focus on particular section.

If I were you I might start with bumping up debug for all components to level 3 (of 9):
debug_options ALL,3

you can keep bumping that up, but if the log gets too verbose for you to parse you might try debugging only the sections that are likely culprits. The list of debug sections can be found in the source tarball under doc/debug-sections.txt . also in Ch. 16 of the O'reilly squid book if you have it (thought the list there is not as up to date)

so for an example, if you were wanted to up the debug level to 3 on just access controls you could try the following:
debug_options ALL,1 28,3

You'll find it's easier to parse these debug messages if you do this in a test or low request volume environment.

Also, do you have any example requests that you expect to cache, but aren't?
