Seems to be an infinite loop

[rodentcentre]

I am coding an ASP page that seems to be going into an infinite loop and I have no idea why. Basically, I have a login page where, well, people log into the system. When a successful log in is reached the Session("UserId") is populated. In all of my subsequent pages I have listed at the top:

<%
If Session("UserId") = "" Then
	Server.Transfer "login.asp"
End If
%>

I have the Session timeout at 20 minutes in IIS so that the user needs to log in again after 20 minutes. Well when the timeout is reached, the user is redirected to the login.asp and the page keeps reloading infinitely...can anyone tell me what is going on??

Make sure that you don't have that same code on the "login.asp" page, or it will "refresh" indefinately.

yup just like bent said:
<%
If Session("UserId") = "" Then
Server.Transfer "login.asp"
End If
%>
the login.asp page shouldnt have this check or it will keep resubmitting to itself...

Known is handfull, Unknown is worldfull

Would

<%
if session("UserID") = "" then
   response.redirect "login.asp"
end if
%>

work?

No, the response.redirect shouldn't make any difference.

I have used a similar approach (mostly to stop people navigating incorrectly into a fairly complex data capture site, for example from the browser history panel). You might want to consider also overriding the default 20 minute timeout.

If you remove that code from login.asp, this won't happen...You don't need it there anyway as far as I can tell.
