The Overview

When developing ASP.NET web applications a very common approach to maintaining state is to store variables into the Session.

Session is just one way to store data. Here are some other ones that I know of. Can you think of any others?

• Application (global) – uses server memory.
• Session (user) – can use user memory and/or database storage.
• Data cache (global, but can be user specific with proper handling) – uses server memory.
• Viewstate (web page) – rides along with the page.  No server memory.
• Database (global and user) – includes SQL, XML, local files, etc.
• Cookie (user) – stored on the client’s computer and accessed via the browser.
• Query String (user) – doesn’t use server memory – just a lot of developer patience.
• Form fields (web page) – popular in HTML and classic ASP development.
