In CocoaEcho (see the link below) its server's Main.m advertises the service @"_cocoaecho._tcp." and its client looks for that service to then make a connection. What is the form of an http service for a web server please? I'd like to substitute that service in CocoaEcho's Main.m on my MacBook so that my IPad's Safari can see it. I think that that would make my MacBook be a WiFi server. http://developer.apple.com/library/mac/#samplecode/CocoaEcho/Introduction/Intro.html Searching the web ... I found CocoaHTTPServer. It builds and runs on my MacBookPro. Question: what address should I put in my IPad Safari in order to see the CocoaHTTPServer please?
