Due to perormance reasons I'm using web gardens (not web farms).  Works great for working around processess that might take long or hang allowing other requests to still be handled.  The issue of course is caching.  Since web gardens work with multiple worker processes not all processes are updated and users experience erratic behavior (sometimes updates appear, sometimes the don't). 

I would think there should be a simple way to invalidate the cache so regardlss of the worker process that is used the application will be aware it's holding an expired copy and refreshes it.  Anyone know an easy way to accomplish this?  Has anyone done it with success?

Thanks for you help.
