When you try to access a Web site on a third-party Web server, you may experience one of the following symptoms after a 30-second delay:
This problem may occur if you use Microsoft Internet Security and Acceleration (ISA) Server 2000 as a Web proxy. When an HTTP POST is sent through ISA Server, and ISA Server is acting as a Web proxy, ISA Server splits the POST into two TCP segments. The first segment contains the headers. The second segment contains the data for the POST. The Web server may respond to the first segment before the second segment has been received and processed.
Service pack informationTo resolve this problem, obtain the latest service pack for ISA Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
