Delayed Response to HTTPS Requests When Proxy 2.0 Runs over IIS 4.0

• Microsoft Proxy Server version 2.0
• Microsoft Internet Information Server version 4.0

SYMPTOMS

When you connect to a Web server through Proxy Server 2.0 installed on an Internet Information Server (IIS) 4.0 computer, the response to HTTPS requests is delayed by about one minute.

NOTE: This behavior is not reproducible when Proxy Server 2.0 is installed on an IIS 3.0 server.

CAUSE

Proxy Server makes a call to IIS to close a client connection. This call returns immediately in the case of IIS 3.0 but takes about a minute in the case of IIS 4.0. This causes the delay in servicing the new client requests.

RESOLUTION

This problem is resolved in Microsoft Proxy Server 2.0 Service Pack 1 (SP1). For more information about Service Pack 1, please see the following article in the Microsoft Knowledge Base:
