Sessions

[aravind_mg]

Hi,
1. I have used session for registering variables and passing them from one page to another. Is there any other way of passing variables?

2. When I use sessions, I encounter a problem when the back button is pressed. I get a session_expired error message. How can this be avoided?

Thanks in adavnce,
Aravind

1. You can pass you variables in cookies or in the URL. But session based variables are safer depending on the data you are passing and your requirements.

2. The back button will do this sometimes with forms on gets and posts. But if you are getting it on standard HTML pages, then look for errors in your code.
