Using ASP
<%
Response.Redirect "redirectpage.asp"
%>
the above redirects immediately; I don't know if you can use it like a
splash screen that then goes to another page after 5 seconds or whatever.
or
Using the meta tag
<meta http-equiv="refresh" value="5; url="redirectpage.html">
This one, you can make it pause before it redirects the "value=5" bit tells
you how long (in seconds) the "url" bit is the page you want redirect to.
The line of code goes in the head along with the other meta tags.
I'm sure Javascript can manage it as well; but I'm not familiar enough with
it to provide an example.
something like Document.Refresh("yourpage"); or something (but don't quote
me on that).
