what's good way to pass variables?

[ralph4208w]

Hi,

I'd like my site to check if a user is logged in. If she/he is not logged in, then redirect the page to a login page, and eventually come back to the originally requested page.

Let's say I have: main.asp?this=2&that=4
the system will see that a login is needed, go to the login screen, see a cookie, redirect to a page that logs the user's entrance, and then finally redirect back to the main page.

What is a good way to pass a querystring as a parameter and then load it later. For example, the login page would see this url: /login.asp?main.asp?this=2&that=4

What is the easiest way to handle this?

Thank you in advance!

you could use a session variable or just pass the extra stuff along in the QueryString... having extra stuff up there wont hurt as long as (1) doesnt get too long and (2) no passwords or other secret data up there in plain text.

Thanks for the reply. Yes, I want to pass it as part of the url. My question: What is the best way to format a passed variable, when the variable contains characters that could be percieved as part of the url? (What is a good way to escape the url characters "&" and "?" when they're part of a variable?)
