Re: Servlets problem in IE4 only

I would like to provide some more detailed informations about my problem
with servlets in IE4, that I posted to the conference some time ago (copy
included). I feel there is some bug in here.

I grabbed the packets of the Jigsaw response to IE. The first contains all
the HTTP headers of the response, and the first part of the data. It's OK.
But, and that is IMO the problem, the second packet, that should contain
only the data part of the rest of the response, are in my packet-grabber
(NetXRay v2.0) viewed also like a headers part (this part includes the
output from the servlet) and data part. I think IE interprets it the same
way as NetXRay does, and that is the problem.

Well, I'm not too skilled in TCP/IP packet structure and rules, but I hope
this info could be helpful to find the bug.

To complete the informations, I have Jigsaw 2.0b1 running by JDK 1.1.6 on
WinNT 4.0
