Using DNN 6.2.0 we have written code at the database level to create a link between Social and Forums i.e. adding or deleting a user to/from a Social group will now perform the same action on a linked Forum.   We have one remaining problem.  Having added the user to a Forum behind the scenes in the database the Forums List View is not showing the user the new forum to which they have been added. Clearing the DNN cache does cause the module to display the new Forum in the user’s list so we believe it to be a cache issue. The cache clearly does not recognise that there has been a database change (fair enough).

We added a custom module to the same page as the Forum ListView.  The custom module calls the methodDotNetNuke.Common.Utilities.DataCache.ClearHostCache(True) and this solves theissue but of course is much to crude as it clears all cached objects in the system.  Ideally, what we need is to beable to clear just the Forum list cache. We have tried calling methods to clear the cache for the tabid and forthe user but these do not achieve what we need (appears to do nothing in fact). 

We assume therefore that the cached forum list is has been cached as a named cache object and that to clear it requires the name.  My request is does anybody know the name of the object or, the line of code necessary to clear the forum list cache?
