I also have slightly different problem about POST. I found that for some
url, such as http://www.geocities.com/cgi-bin/homestead/file_manager.html,
transparent proxy user can't submit the from from that page. access.log
has the following entry logged (after a long timeout):

907575865.145 44000 203.155.35.200 TCP_MISS/000 0 POST http://www.geocities.com/cgi-bin/homestead/file_manager - CLOSEST_PARENT/proxy3.ksc.net.th -

and user got read timeout error. proxy3.ksc.net.th was sibling of this
cache (proxy1). After I added the following lines to squid.conf, the
problem solved:

acl POST method POST
cache_peer_acl proxy3.ksc.net.th !POST

both proxy1 and proxy3 are running squid-1.2b22, though. The strange thing
is that why proxy1 send query to proxy3 even though I already have
following lines:

hierarchy_stoplist cgi-bin ?
