All editions allow you to open and check URLs. To do this, the document must first be opened from the web and the source must be visible in the editor. You can do this by choosing File->Open from the Web. You will need an active network connection when opening documents from other computers or from the Internet. Once the document has been loaded into the editor, it can then be validated as if it were a local document or file. However, editing and saving the document will not change the document that was sent from the server. You will have to change the original document that is normally located on the web server. Often times this is done by uploading the file to the web server by using an FTP program.

(Pro, Std, Lite) Another way to check URLs and dynamic sites is to use the integrated web browser available in the standard and professional editions. While browsing with the integrated web browser, the source for the document being displayed is shown in an editor tab and can be easily validated. As you navigate through the web, you can also have the source automatically validated after each page is loaded. To do this, make sure that this feature is checked in the Editor Options. Using the integrated editor is a great way to check a website with dynamic pages such as those made by ASP, CFML, or PHP scripts.
