I have a VS 2008 Web application that accesses an environment variables using Environment.GetEnvironmentVariable.  When I test in Visual studio it works fine.  However, when I deploy and test through the Cassini web server, the environment variable is returning null. In VS I had to restart VS before it could see the new variable.  I've restarted the UltiDev service, but that did not work.  Should this work through the Cassini webserver?  I am really hoping to not have to use IIS.
Thanks,
M
