Use of HttpProxy results in System.TimeoutException

[Matt]

I would like to use the HttpProxy to add a special http header when performing a test.  However, I am not able to execute a simple test using the HttpProxy.

Whenever I set the UseHttpProxy value to true, my test will fail with a System.TimeoutException.  A popup window  "ArtOfTest.Runner has stopped working" message appears.

the browser does navigate to the page.  I can view the page in the browser.  At the end of the test, the crash occurrs.  The test does not fail if I remove the UseHttpProxy line.

System configuration...
Test Studio 2011.1.609.0
Running Windows 7 Pro 64-bit SP1
4GB RAM
Added ArtOfTest.WebAii.HttpProxy.exe and ArtOfTest.Runner.to windows firewall exceptions

Test setup...

[CodedStep(@"Navigate to : 'http://www.mckerinsoftware.com/'")]
public void apibranchtest_CodedStep()
{
         Manager.Settings.Web.UseHttpProxy = true;

         // Navigate to : 'http://www.mckerinsoftware.com/'
        ActiveBrowser.NavigateTo(http://www.mckerinsoftware.com/);
}

Log entry...

Overall Result: Fail
System.TimeoutException: The operation has timed out.

Other note...
On the Help menu when I View the Application log, I see the following message even during a successful test when the UseHttpProxy line is commented out.  I do not know if this is related, but wanted to provide as much info as possible to help with a resolution.

Error: PipeCommunication.AsyncPipeRead() : EXCEPTION ("Pipe Null State: False")

Hello Matt,

I am sorry for the confusion. The UseHttpProxy must be set before the browser is launched. By the time a coded step gets control it's too late. You have two options to overcome this:

1) In your closed step. Close and reopen the browser using code like this:

ActiveBrowser.Close();
Manager.Settings.Web.UseHttpProxy = true;
Manager.LaunchNewBrowser();

2) Set SilverlightEnabled as shown in the attached screenshots. Even though you may not be using Silverlight, it has the side effect of turning on our HTTP proxy which our Silverlight automation depends on.

Thank you!  That works great.  I appreciate the help.
