What I want to do is, instead of a redirect of the traffic that goes to these short URLs, to be forwarded to a page with a frame on top that I can place ads on.

 

[frank-germany]

thats a completely different setup

here is the basic code

-----
<html>
<head>
<title>Example - Frames</title>
</head>
<frameset rows="100,*">
<frame name="top" src="frames_top.html">
<frameset cols="50,*,50">
<frame name="left" src="frames_left.html">
<frame name="mid" src="frames_middle.html">
<frame name="right" src="frames_right.html">
</frameset>
<noframes>
<i>error to display to those who cannot see frames</i>
</noframes>
</frameset>
</html>
----------------

your code would then go into frames_middle.html

 

[Mr. Deleted]

would you be able to modify it for me?

 

[frank-germany]
