RewriteRule help please

This should be easy, but I'm missing something. In my local
environment I want (and have) a DNS alias 'wiki' that points
to one of my linux boxes. When a user enters 'wiki' in the
address bar of the browser the user is pointed to the main,
home page on the linux box. I want a RewriteRule (I think
that's what I want) that converts http://wiki to
http://inside/twikib/bin/veiw/Main/Webhome.

Here are the two rules I tried that did not work:

RewriteRule ^http://wiki/?$ http://inside.pointwise.com/twikib/b...w/Main/WebHome
RewriteRule ^/?wiki/?$ http://inside.pointwise.com/twikib/b...w/Main/WebHome

httpd 2.0.46
Red Hat Enterprise Linux ES release 3 (Taroon Update 5)
firefox 2.0
