Hi,

hat jemand Erfahrungen mit Windows Sockets sammeln können? Ich hab hier nen
kleinen Webserver, welcher auf einfache HTTP Anfragen reagiert
(CBlockingSocket). Leider ist es aber so, daß die Sockets nicht richtig
geschlossen und wieder freigegeben werden. Laut shutdown und close werden
alle Sockets fehlerlos geschlossen. Jedoch sagt netstat etwas anders:

 ...
 TCP server:80 client:4699 TIME_WAIT
 TCP server:80 client:4701 TIME_WAIT
 TCP server:80 client:4702 TIME_WAIT
 TCP server:80 client:4706 TIME_WAIT
 TCP server:80 client:4707 TIME_WAIT
 TCP server:80 client:4709 TIME_WAIT
...
 TCP server:80 client:4722 TIME_WAIT
 TCP server:80 client:4723 TIME_WAIT
 TCP server:80 client:4724 TIME_WAIT
 TCP server:80 client:4726 TIME_WAIT
 TCP server:80 client:4729 TIME_WAIT
 TCP server:80 client:4731 TIME_WAIT
 TCP server:80 client:4735 TIME_WAIT
 TCP server:80 client:4736 TIME_WAIT
 TCP server:80 client:4738 TIME_WAIT
 TCP server:80 client:4739 TIME_WAIT

Das geht dann soweit das nach einer gewissen Zeit der Server "hängenbleibt",
da unzählige Ports immernoch warten... Vielleicht weiß ja jemand, wie ich
dies verhindern kann?

Der Server soll auch unter WinNT und 9X laufen...

Besten Dank,

Holger Kreißl
