The IsWebFarm setting is one of the
AppSettings that can be added to the web.config file. By default IsWebFarm is not included in the web.config and defaults to false. If your site is configured to use the
FileBasedCachingProvider and IsWebFarm is set to true, then the framework will ensure that all servers in the farm keep their caches in sync.
The IsWebFarm setting is not applicable if any caching provider other than FileBasedCachingProvider is used.
This setting replaces the
EnableWebFarmSupport setting that provided the same function in DotNetNuke 4.x.
