Understanding relative and absolute file addressing
It is common to develop a Web site at your desktop computer or laptop computer at home or work. At some point, however, the pages you develop for your Web site will have to be published (uploaded) to a file server so that the pages can be viewed on the Web. Expression Web uses relative file addressing, in which a file is linked in relation to another file at the same Web site and stored in the same folder on the same computer or on the same file server. An absolute file address specifies the entire directory path to a linked file. If you are developing a Web site on your desktop or laptop computer, don't use an absolute address to point to a location on your computer for your links. If you do, the links won't work once the page has been moved to the server, because the path that leads to those files or images will no longer be correct. It's okay to specify an absolute address if you are familiar with the directory structure of the server, but you don't want to specify a path that refers to a folder on your desktop computer. If the link is to a file on a different file server or at a different Web site, the link must contain an absolute file address, like so: http://www.ford.com/index.html.
