I know little about networking the Internet, but, from what I understand, it works — very approximately — as follows:
- I, sitting at the computer
example.com, send a message saying, roughly, "get
http://s.tk" to my ISP, which passes the message along, eventually to the machine at
s.tkmachine gets "
example.comhas sent 'get
http://s.tk'", so sends
somefileto its ISP which passes the file along, eventually to the machine at
When the file gets back to
example.com, my computer, how does my computer know what to do with it? I'm sure the headers (or something else) indicate it's a Web page rather than, say, a Usenet post — that's not my question. My question is: how does my computer know whether to display the received Web page in my open Opera window or my open Firefox window, or my other open Firefox window, or, heck, to open a new browser instance?
