Some parameters in a query string are not parsed correctly in a hyperlink to an ADFS-enabled Web site (921240)


The information in this article applies to:

  • Microsoft Windows Server 2003 R2 Datacenter x64 Edition
  • Microsoft Windows Server 2003 R2 Enterprise x64 Edition
  • Microsoft Windows Server 2003 R2 Standard x64 Edition
  • Microsoft Windows Server 2003 R2 Datacenter Edition (32-Bit x86)
  • Microsoft Windows Server 2003 R2 Enterprise Edition (32-Bit x86)
  • Microsoft Windows Server 2003 R2 Standard Edition (32-bit x86)

SYMPTOMS

The parser of an Active Directory Federation Services (ADFS)-enabled Web site will only parse the first parameter in the query string of a hyperlink. This problem occurs when the query string includes multiple parameters. Additionally, this problem only occurs if the user account has not gone through realm discovery. Therefore, the user account currently does not have a persistent cookie. For example, you will experience this problem when you have a hyperlink to a Web site that resembles the following:

http://www.contoso.com/query.asp=param1&param2&param3

CAUSE

This problem occurs because the parser incorrectly parses the HTTP POST body content. In the HTTP POST body content, the symbol "&" is used as a delimiter between specific parameters. The parser incorrectly interprets the symbol "&" in the URL and truncates the URL.

Technical support for x64-based versions of Microsoft Windows

If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
