I have an ASP.NET MVC website in IIS named 'Website' using an AppPool named 'WebsiteAppPool'. WebsiteAppPool is configured to allow up to 4 Worker Processes, in effect creating a 'Web Garden'. The Website is also configured, via web.config, to enable OutputCaching using CacheProfiles.
<caching> <outputCacheSettings> <outputCacheProfiles> <clear /> <add name="ControllerNameActionName" duration="43200" varyByParam="*" /> </outputCacheProfiles> </outputCacheSettings> </caching>
My question is -
Will the AppPool's worker processes share the output cache or will each worker process have the Output Cache, therefore creating 4 cached copies across the AppPool.
My main concern is that this will debunk the benefits of having cached output and I would be better off having one WorkerProcess serving up the cached output rather than the 4.
