[-- Attachment #1 --]
I have been looking at the following snippet of packets
(under FreeBSD 6.1).
This makes IE7 fail (but not IE6) with a generic error.
We see lots of strange things here.. (like, why does the RST
go to a different sequence number?)
What we are having problems with is:
What SHOULD the server be doing in response to the extra 2 bytes
it receives after it has sent the FIN?
I would LIKE to be able to make this work, but I don't personally
have the influence to fix IE7 so I'm left to
do what I can on the server (port 3128) end.
The FIN from the server is generated when the server closes the socket.
