Hi, Peter--
The string "X-SERVERSOCKET: REUSE ServerPipe#1321REUSE ServerPipe#384*NEW*" means
"First we attempted to reuse the connection to the server established in session #1321. But that connection did not work (e.g. calling Send with the new request on the existing socket failed). So next we attempted to reuse the connection to the server established in session #384. But that connection didn't work either. So, having run out of available established sockets to reuse, we instead tried establishing a NEW connection to the server and using that connection."
If that third attempt fails, Fiddler doesn't retry another NEW connection; the error is fatal because only one NEW connection is permitted per request.
Regards,
Eric Lawrence
