maybe you got some experience dealing with IE9, i have a weird issue.

let me show you how my server interact with quetannon, so we got some idea how things works.
Code:
[A]      s[216]
[R]      s[216]
----------------------------------- recv : 29 bytes
hello world from quetannon.

[C]      s[216]
    


i start the server, open IE9, browse to http://localhost,
stop the browser, and then finally close the browser.
Code:
[A]      s[212]
[A]      s[220]
[R]      s[220]
----------------------------------- recv : 239 bytes
GET / HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Accept-Language: en-us
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0)
Accept-Encoding: gzip, deflate
Host: localhost
Connection: Keep-Alive


         s[220] WSAGETSELECTERROR - 0X2745
[C]      s[220]
         s[212] WSAGETSELECTERROR - 0X2745
[C]      s[212]
    


if i didn't close the browser, socket s[212] wouldnt get closed

why IE9 make 2 sockets connection, either one send GET, another one sent nothing.


firefox pattern
Code:
[A]      s[212]
[R]      s[212]
----------------------------------- recv : 284 bytes
GET / HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (Windows NT 6.0; rv:18.0) Gecko/20100101 Firefox/18.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
DNT: 1
Connection: keep-alive


[C]      s[212]

Probably some kind of optimization. Why don't you set a breakpoint on socket creation in iexplore.exe (use windbg), load the public symbols (srv*http://msdl.microsoft.com/download/symbols), and look at the stack? The names of the routines will give you a hint as to what it is doing.

wow, i think that is beyond my capability, =(

optimization, maybe, i notice for 2 attempt to access http://localhost on 2nd tab, it uses the s[212] socket,

maybe this is designed by IE team, probably, i guess,

i will try force close the socket and see if IE crashed.
