Localhost with custom port fails to load

[kballard]

When I type the string "localhost:3000" into Safari's URL bar it loads "http://localhost:3000" just fine. When I paste it into OmniWeb it fails - I think it's trying to load a URI with the scheme "localhost" and the resource "3000'. Typing out "http://localhost:3000" works fine, though.

That's strange; I get the same thing. I used these to test it; they should be on everyone's machine: the CUPS admin page (http://localhost:631/) and the launchd page (http://localhost:12345/) (which might disabled by default).
