Absolute paths provide the complete URL of the linked document, including the protocol to use (usually http:// for web pages), for example, http://www.adobe.com/support/dreamweaver/contents.html.

You must use an absolute path to link to a document on another server. You can also use absolute paths for local links (to documents in the same site), but that approach is discouraged—if you move the site to another domain, all of your local absolute-path links will break. Using relative paths for local links also provides greater flexibility if you need to move files within your site.
