When i sniff the traffic the IIS never sends [FIN,ACK] nor [RST,ACK] packet. I created a script that looks for special word in the reply page to identify the server it comes from so here are the reports from few tests when i go trough IIS:

Also i used WMI script. from my desktop to test it. There i see [SYN] at the begining of each request and[RST,ACK] at the end as well as each request increments the port it is comming off of. Here is how the CSS act in this situation:
