Web farm getting out of control? You need scalability! SA-SessionPro is a simple, yet
very powerful means of making your ASP application persistent--share and save
information on a per-user, per-application, per-server, or per network basis. SA-Session is
like the built in Session object that comes with the IIS Server, except it allows developers
more flexibility. It has the ability to store information without expiration and the ability to
preserve session state across multiple machines in a web farm.
SessionFarm is an Active Server Pages component that allows you to manage session state on multiple servers in a web-farm. SessionFarm utilizes the built-in IIS Session object which means you don't have to learn new methods
and objects. The IIS Session object is stored on either a file-share or a SQL database using optimized stored procedures.
SessionFarm requires no rewriting of your existing code and works by supplementing the existing IIS Session.
