URLs have the following components: http://www.example.com/path/file.html?a=value#target http:// Protocol: Tells the browser how to communicate with the server. www.example.com Host name: Tells the browser where on the internet to go. /path/file.html Path: Tells the server what file was requested. ?a=value Query string: Tells the server what information is requested. #target Hash: Tells the browser where on the page to go The component we're dealing with here is the hash. When you click on a link with a hash in it (<a href="page.html#something">) it scrolls you down to the e
