I'm russian, so sorry for bad english...

Got problem with DotNetNuke.Caching.FileBasedCachingProvider and rewrite code.

Situation: all working correct, except UsersOnline. Looking like no one entered into. In debug i found, what Cache.Insert Function with default parameters store nothing.

Solution: changed parameters. Code changes highlited:

Public Overloads Overrides Sub Insert(ByVal CacheKey As String, ByVal objObject As Object, _
                ByVal objDependency As CacheDependency, ByVal PersistAppRestart As Boolean)
            Insert(CacheKey, objObject, objDependency, System.Web.Caching.Cache.NoAbsoluteExpiration, TimeSpan.Zero, PersistAppRestart)
        End Sub

defaultly used Datetime.MinValue produced imediately cache cleanup or store bypass. Name it as u wish.
