I'm looking for a best of both worlds solution.  I need the web garden due to busy processes caused by heavy traffic. Is there a way to invalidate the cache using the file update model?  This is suppose to work with Web Gardens.  The down side is a bottle neck can be created when a file is locked by SQL Server and other processes have to wait for the release.   This wouldn't be a big problem in my case since not many of the users update the dnn portal.  I just need to have some means for a Worker Process to know it has an old version so the users don't get the annoying sometimes you see the changes sometimes you don't problems we currently have.

Has anyone done this yet for DNN?  If so please share

Thanks,

Scott
