[squid-dev] [PATCH] adapting 100-Continue / A Bug 4067 fix

[Tsantilas Christos]

Hi all,

This patch is a fix for bug 4067:
     http://bugs.squid-cache.org/show_bug.cgi?id=4067

Currently squid fails to handle correctly "100 Continue" 
requests/responses  when adaptation/ICAP  is used. When a data-upload 
request enters squid (eg a PUT request with  "Expect: 100-continue" 
header), squid sends ICAP headers and HTTP headers to ICAP server and 
stuck waiting for ever  the request body data.

This patch implements the "force_request_body_continuation" access list 
  directive which controls how Squid handles data upload requests from 
HTTP and send the request body to Squid.

An allow match tells Squid to respond with the HTTP 100 or FTP 150 
(Please Continue) control message on its own, before forwarding the 
request to an adaptation service or peer. Such a response usually forces 
the request sender to proceed with sending the body. A deny match tells 
Squid to delay that control response until the origin server confirms 
that the request body is needed. Delaying is the default behavior.
