I have a Windows Server 2008 R2 SP1 box with IIS 7.5.7600.16385 installed.
I have HTTP Keep-Alives switched off. Each time a web-request is made the connection is terminated.
I get the following packet trace:
I can see a FIN,ACK going from the client to the server, but none transmitted in the opposite direction.
If I try this from other machines with a supposedly identical configuration the FIN, ACK is transmitted in both directions.
I can't work out what the difference is? Is there any way of configuring this behaviour?
