When authenticating a user, it doesn’t assign a new session ID, making it possible to use an existent session ID. The attack consists of obtaining a valid session ID (e.g. by connecting to the application), inducing a user to authenticate himself with that session ID, and then hijacking the user-validated session by the knowledge of the used session ID. The attacker has to provide a legitimate Web application session ID and try to make the victim's browser use it.

I was using Visual Studio 2010.  I was debugging a web application and an exception happened and VS 2010 froze.  I ended the VS 2010 in the task manager and when I went back to developing, I found on every form for every ASP.net control I get:  Error Creating Control - Error HRESULT E_FAIL has been returned from a call to a COM component.  Also I am unable to edit  the form or add anything from the toolbox. Solution: This error comes because of Caching of Visual Studio Delete the Cache. You can delete the project cache at "Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache", then run "devenv /setup" to build the cache again to see if it helps.
