TCP connection window size change question

[George Vandelet <george_vandelet () yahoo com>]

Wireshark superusers,

I have been looking at captures and many times I see at the end of an TCP HTTP 
session a TCP packet (or series of TCP packets) that looks to (in wireshark) 
change the window size.  Why does wireshark show that the window size changes 
right before the TCP session is closed?  It does not make sense to change the 
window size after the first FIN,ACK ->ACK exchange has been done as there is 
nothing to do after that except for close the connection with the following 
FIN,ACK ->ACK! 



Thanks!

George
