More information:
In order to maintain client session state within a web application that is hosted in a server farm environment a method of storing state must be designed and implemented. Within a Microsoft environment, session state can be stored in a number of ways, each with it's own pros and cons. The use of ASP Session variables is the easiest to use, but the least scalable. Querystring and form information are the most scalable, but they can be difficult to use and are totally unsecured. In order to find a compromise between the available session persistent methods, the xmlSession component was created. This component will provide the web developer with method to easily maintain session state without the scalability problems associated with traditional session variables. All "session" information is stored in a centrally located data store (file or database) that can be accessed by any server in the farm.

Notes: Windows 2000 and version 3.0 or higher of the Microsoft's XML object model is required. Complete documentation is included. There is also a test vb project and and project group (.vbg) included in the test directory. Running the test project and stepping through the code will give you an idea of what the module does.
