100-Continue Error





------- Additional Comments From [EMAIL PROTECTED]  2003-03-10 17:21 -------
Several observations can be made analysing squid access log attached above:

1) Mozilla 1.2.1 appears to not be using "Expect: 100-continue" handshake when 
sending POST requests via HTTP proxy
2) Squid does not seem to honour "Expect: 100-continue" protocol. Squid happily 
returns 100 status code and closes the connection to the remote host.

The question here if who is at fault here: Squid or HttpClient? Can it be that 
Squid expects additional conditions to be met, for instance [Proxy-Connection: 
keep-alive\r\n] is expected to be present?

Regardless whose fault it might be, I suspect many HTTP proxy may have various 
issues with "Expect: 100-continue" handshake. To be on a safe side, I 
suggest "Expect: 100-continue" handshake be disabled when sending entity 
enclosing requests via a HTTP proxy.

Comments, ideas, suggestions?

Oleg
