ISA Server 2006 does not pass the last server cookie to the client computer when HTML form authentication is used in the Web-publishing rule

View products that this article applies to.

Symptoms

Consider the following scenario:
  • In Microsoft Internet Security and Acceleration (ISA) Server 2006, you configure a Web-publishing rule that uses HTML form authentication.
  • You browse to the published Web server from a client computer.
  • The Web server replies with a "401 Unauthorized" response that includes several server cookies.
In this scenario, the client does not receive the last cookie from the server response. This behavior may break the application layer protocol between the client computer and the published Web server.

Cause

This problem occurs because the Forms-Based Authentication filter incorrectly parses the server response. Therefore, the filter misses the last cookie.
