No defaulting to HTTP on non-standard ports

If I put in a URL like: 192.168.0.17:8023 in IE, it craps out. Stick an http:// in front of it and it works just fine.

Now, I know that ports 8023, 8042 and 8093 don't mean HTTP. However, if I use a web browser to test sites on those ports, shouldn't it at least give HTTP a try? Call me a lazy bastard (and rightly so), but I don't feel like typing in http:// every time I type in a domain with a non-standard port...
