There is three main cases to why Squid does not cache all http
request:
a) The server has marked the reply as not cacheable. See the
cacheability check engine (linked from Related Software).
b) The client requests a fresh copy not from cache.
c) The server did not provide any relevant expiry information, making
Squid assume the object is dynamically created.
For detailed analysis on what is your case, enable log_mime_hdrs, and
then send a log with two requests
1. The first request, which supposedly should have made the obejct
cached.
2. A second request, which supposedly should have been a HIT but which
was a MISS:
