Chapter 3. Advanced DHTML Techniques > Storing Data in URLs

Storing Data in URLs

URLs provides a unique “address” for all of the billions of Web pages. However, a URL can also contain strings of information, inserted after a question mark, which can then be interpreted by the page being loaded. These data are not literally a part of the URL and do not affect what page loads, although they can be used to affect the content on the page in a variety of ways.

In this example we will be using the URL method to pass form data from page to page. This allows us to create a multipage form rather than placing everything on one page.
