login redirect

I want to know what I need to include in my login script to redirect the user back to the page they were trying to access.
For example, if a user wanted to access a directory with permission levels and they were not logged in they would be sent back to the login page and after they logged in they would be redirected back to the directory. I also want to make sure they are not redirected to an outside site if they had the directory bookmarked.
Can anyone help?

Thanks, but lets say someone has to login before they download an application and there is no intForumID then what do you do?

I am not 100% sure, but the HTTP_REFERER only keeps your previous page in memory. When you login, well thats two tries is involved and your refere has changed. I would just suggest just pass two values, section you are clicking the like, like Download, and the ID number you are clicking, then after logging in, just redirect to that page. The same way you can do it to different sections, just doing, select case statement.

Good ideas, one good way to do it would be to use the SCRIPT_NAME servervariable in the page that requires to be logged in and put it in a variable and pass it as a querystring back to the login page.

For Example:

<%
Dim strRefUrl
strRefUrl = Request.ServerVariables("SCRIPT_NAME")
If Request.Cookies("PollAdmin") = "" Then
Response.Redirect ("login.asp?ref=" & strRefUrl)
End If
%>
