HTTP pipeline request might cause TCP window stay at 0 and not recover.
When this occurs, the resulting TCP zero window suspends data transfer. It is possible that the TCP window will be reduced to 0 (zero) and never recover.
This intermittent issue occurs when HTTP pipeline requests are sent, and those requests use the GET method.
None.
HTTP pipeline request no longer causes TCP window stay at 0 when HTTP pipeline requests are sent, and those requests use the GET method.
