I've read all the articles about how session variables are evil and that I should be using cookies instead. In most cases I agree but I do have a question about session variables. In some cases it's just plain easier for me to use them I just want to know something while they are on the site and I don't need to store that in a cookie. My question is: If I've got 2 or 3 or more session variables set per user at a time - is that really hogging up server resources. If I have a ton of people on the site would it really cause a slow down?
