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?)

figured that one out... it's using the latest ACK value from the client..



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.

note: IE7 never sends a FIN. (IE6 does)
