A system and method are presented that enhance the performance of single and
multiple-processor
servers by taking advantage of the half-duplex nature of many HTTP requests. Upon
receipt of an HTTP Get resource request, a single send and disconnect IRP is generated.
The semantics of the send and disconnect IRP completion recognizes the half-duplex
nature of the transaction by indicating a graceful close of the TCP/IP connection.
This send and disconnect IRP is also completed without a queuing stage (queuelessly)
on the processor that serviced the client request. To further enhance performance,
the server FIN message to the client is included in the last data frame transmitted
to the server. The invention also contemplates transmission of a single HTTP get
and disconnect request by a client to allow acknowledgementless disconnection of
the TCP/IP connection once a requested resource has been sent.
