SYMPTOMS
When you record a Web test in Microsoft Visual Studio 2005 Team System Test Edition, you may receive the following error message:

Request Failed: Index and length must refer to a location within the string

This error message may appear in the following tabs of the Visual Studio Team System Test Edition IDE:
 * WebBrowser
 * Response



CAUSE
This problem occurs because the .NET Framework 2.0 client fails with an exception. In particular, the following exception may occur when you record a Web Test:

System.ArgumentOutOfRangeException: Index and length must refer to a location within the string

This exception occurs if the server content-type HTTP response header of the Web page contains a repeated property-value pair. For example, the following HTTP header contains a repeated property-value pair: Content-Type: text/html;charset=UTF-8;charset=UTF-8.
