URL

URL is short for Uniform Resource Locator. A URL includes the domain name, the path, and the file name.

Examples:
www.postcardimaging.com/images/sitelogo.jpg
www.postcardimaging.com/index.php

You can look at a URL as a universal way for someone to find a file, an image, or even other more complex objects. Universal means that anyone on the Internet uses the same path to access this file or object.

For Advanced Use

Technically, the url should include the protocol at the front, for example http:// or ftp://, but there are actually quite a few other protocols. Also, at the end of a file name, there are two more advanced features a URL can have: 1) a Query String, which is a series of variables after a question mark (?), and 2) a bookmark or anchor, which comes after a pound symbol (#). A Query String is a way to pass values to the page which can do special things, and a bookmark marks a specific spot on a long page, so the browser can move the page directly to that spot. The Query String always comes first, then the bookmark

Example 1: http://mysite.com/members/mypage.htm#section3 (takes you directly to section 3 on the page)

Example 2: http://mysite.com/members/mypage.htm?name=Sam&logincode=184

Example 3 (combined): http://mysite.com/members/mypage.htm?name=Sam&logincode=184#section3
