cc'ing to squid-dev where the people who might know reside....
Also, adding "debug_options 11,2" may show something useful in the HTTP
flow for 3.2.

Hi,
Objects don't get cached in Squid 3.2. Same transactions and config
works in 3.1
I will show my problem with a simple webserver listening on
127.0.0.1:9990
and sending transactions from curl to a squid listening on
127.0.0.1:9993
3.1 logs first a MISS since the cache is empty and when repeating the
transaction a HIT.
3.2 logs 2 MISSes

To repeat : Squid 3.1 logs expected MISS + HIT while 3.2 logs MISS +
MISS.
Does anyone have any idea what I am missing here ?
