[squid-users] "POST" method doesn't work on Squid 3.0 Stable 7(+ ICAP client) and GreasySpoon (ICAP server)

Thanks to developers' hard work to let us enjoy the Squid. Currently,
I am using Squid 3.0 Stable 7 + ICAP client and GreasySpoon (ICAP
server) to customize the page. It works pretty well in Debian.

However, when I browse the page, which has a form with "POST" method,
the page will load repeatedly without finishing, such as
http://www.redbox.com/Titles/Availabletitles.aspx. (The "POST" method
can work well if I disable ICAP client inside Squid.) I search for the
mail archives for a while, but cannot figure out if that is a ICAP
client problem.

I check the Squid log and GreasySpoon access.log and found following messages:

============================================================
Squid access.log

1215807898.875 313 XXX.XXX.XXX.XXX TCP_MISS/200 751 GET

GreasySpoon access.log:

ICAP/200 HTTP/POST http://XXXXXXX/confirm.php
============================================================

However, I don't see any POST http:// xxx in squid log, which might be
the reason to cause the page to load repeatedly. (But I can see TCP
package [TCP segment of a reassembled PDU], which contains Post method
message.)

Does anyone encounter similar problem with ICAP client? I appreciate
anyone who can give me some suggestions or point me to past related
mail to know how to fix it. Sorry if this is a repeated question.

Thanks for any suggestion.
