Selenium and IIS7

We had a minor victory this morning. We finally got Selenium working under IIS7.

Apparently Selenium doesn't like IIS7's new managed pipeline. Neither does Reporting Services 2005 -- but that is another story.

So the fix: Open up the IIS Manager (InetMgr.exe), open up "Application Pools", you should see DefaultAppPool. Double-click it. The last option on the dialog should be "Managed pipeline mode", select classic (it should be Integrated by default).

You can read about what changed in the March 2007 issue of MSDN Magazine article: Explore The Web Server For Windows Vista And Beyond (http://msdn.microsoft.com/msdnmag/issues/07/03/IIS7/)

Skip down to ASP.NET Integration so see how the pipeline has changed.

The real nice thing is that with IIS7, yes they made a number of changes that seem to break a number of web application, but they did give us a way back.
