I'm caching quite a lot of datatables using asp.net caching (the floowing code):\[code\]HttpContext.Current.Cache.Insert(GlobalVars.Current.applicationID + "_" + cacheName, itemToCache, null, System.Web.Caching.Cache.NoAbsoluteExpiration, TimeSpan.FromMinutes(240));\[/code\]However I think that the cache on the server is getting full and having to re-obtain the datatable data from the database. Is there any limit to the amount of data that can be cached on the server or any IIS settings that can be tweaked?
