I user Sessions. Basically, when a user logs in , i carry the Username, to Display a message like Welcome "James" and each and every page i check if the Session is new, that means i chech if the Session variable is empty if its new, the user must be redirected to the login page. Now when the User logs off , i abandon the Session. Hope it helps

As the others have mentioned, use session variables. Do make sure when you are done with the user's session variable to delete it when finished. Otherwise, you will eventually (as this may take a very long time to have happen) run out of memory on the server where the values are kept.

The one step no-one else mentioned, is to create a new base page, which redirects to the login page if the user is not already logged in. From there, it just works.

Would you believe I inherited a project that didn't bother to do this ? If you went to a URL inside the site directly, it would just work, or blow up on the basis of missing sessions variables ( not the login, all sorts of other stuff was being stored in the session and never checked when it was accessed ).

Oh boy, I bet that was loads of joy fixing that up.

That was just one example, that whole site was a nightmare. The other big thing that blew my mind was that all session variables were strings, and all strings were typed in everywhere. I actually found code like this: if (Session["WeShouldDoStuffNow"] == "YES") when doing some searching proved that it was only ever set to Yes, or No. I obviously centralised all the 'WeShouldDoStuffNow' values to a class, so that there were never typos, but I gave up, I defined YES and NO rather than move to bools.

Those can be a problem. Session variables are going to be a part of my discussion this up coming Tuesday evening in my VB.NET class I teach. I try to emphasize the importance of doing something like:
Dim MyUser As String = "UserName" If Session[MyUser] blah blah blah blah Then ....is easier and safer to work with than having the variable name inside quotations. It is a point I try to get across, and usually get mixed mileage every semester.

Yeah, I would create a class that contains all the strings, and use it throughout the site. It's hard to believe that anyone would fail to understand how important that is, once it's explained to them.

Hmmmm, that sounds like a nice little final exam problem [evil grin]...

It happens from time to time, usually the student who is too busy IM'ing someone and not paying attention to the discussion. After they spend about two hours trying to debug the errors caused by the typos, it finally clicks.
