Using Sessions in ASP

Sessions are a safer, more effective alternative to cookies. This tutorial will teach you how to use sessions in ASP.

Sessions are defined as a unique visit to a particular website and it's child pages. Each session can contain data, and the data in the session variables are user-specific. This data is stored during the entirety of the session, and is only accessible by the ASP pages which the user views or executes. How can ASP sessions be useful? Take an example: you have a large website with many users, and a user decides to log on using his username and password. How can you store this data for the entirety of his visit? You have two plausible choices: Cookies, and Sessions.
The advantage of using cookies is that once he logs in, the cookie stores the visitors information on that computer for as long as the duration of the cookie, even if the session is over. For example, if he logs in and browses around your site and then closes IE, and comes back tomorrow to your page, it'll still remember his name and password. The obvious disadvantage of cookies is that it's a security hazard. Also, some people have cookies disabled so it may not be a viable solution. ASP Sessions are a safer, guaranteed working method of storing variables in ASP throughout the duration of the visitors stay.
Because sessions automatically start upon the users arrival to the site, we don't need to declare that session variables will be used.
Here we store a username "Bobert" into a session variable:

<% Session("username")="Bobert" %>

Think of Session("username") as any other variable. you could just like you could any other variable.
If you want to destroy the contents of a session variable, you can use this piece of code:

<% Session.Contents.Remove("username") %>

And if you want to destroy the entire session prematurely, you can use this:

<% Session.Abandon %>

I hope you find this a safe yet effective way to store data such as a username or password.
