Need help with configure.php

[m82492]

A scpript I'm loading is asking me to edit the configure.php files in under Admin and under Includes in the script. It is asking for something I'm sure is quite simple but I can't figure it out. It wants the address for the http_server and the http_catalog_server ??? Are these addresses to my hosting or my actual domain name? I'm assuming it's looking for some address from my hosting but I have no idea where to find it or what it would be called.

Have you tried localhost ?
