This is from another post of mine here in the NewsGroups and thought it answered your question as well
In a Windows application context information can be stored in the AppDomain.CurrentDomain which inherits from System.MarshalByRefObject, which is completely different object hierarchy for the web world. So in order to have your application work accross both platforms you must create an abstract layer for your context and your application will interact with the abstract/interface object. To accomplish this you will need a factory object that determines what environment you are in and call the appropriate class to return the abstract context. Here is a code example in C#, error handling and comments were not included in order to keep the size of the post small. All you need to do is implement the concrete class for dealing with the web environment. Constructive critisism is welcome
