I was trying to learn about servers, I don't know anything about php or servers, except for HTML.

I'm having a problem with apache (I never knew Macs came with a server). I'm nervous that I may have screwed up something with the Apache.

I turned on "Personal Web Sharing" and have OS X v10.4.10, did the exercise "Gleefully Served by Mac OS X". I see the page in Safari browser if I type in /Library/Webserver/Documents/ but not if I type in http://127.0.0.1/

If I do that, I keep getting a message "cannot connect to local host"

The internet is shared by 2 computers, one a pc and this mac.

Is there a way to resolve this?

Thanks for any advice
