Good good - always good to try and better your own programming skills!

This sounds like your login page and your welcome pages both have headers
(the same?)?

No no - heres a short run down for you :
Response.redirect - the server sends a message to the web browsers, which in
turn sends a message back to the web server asking for the specified page.
This is like loading a new page - but without the user clicking on anything.
(client side re-direct)

Server.transfer - the server includes the called page into the current page.

Similar to response.redirect - but it allows the called page access to all
variables and request collections, and the user does not see any difference.
(server side redirect)

For example if I had :

a.asp
<%
response.write("1")
server.transfer("b.asp")
response.write("3")
%>

b.asp
<%
response.write("2")
%>

when a.asp is called the output would be
12

notice 3 does not get written - this is because the calling page (a.asp)
does not regain control after the called page has finished executing.

Hope this has helped a little.
