Hi John,

I don't think that case (1) redirects - see eprints3/cgi/users/home. It 
just passes on the request to the ScreenProcessor. You could achieve the 
same with a trigger in fact.

Since your screen already has a url 
(http://repo/cgi/users/home?screen=MyScreen), I guess what you want to 
do is a rewrite as in mod_rewrite.
