You add an action attribute to the form to define where the submitted data goes. In the example above the submitted information will be handled by the script of the home.html document.

In this case, the URL is called relative. Relative URLs are compared to the current URL that is loaded in the Web browser. We can use slashes and the “double dot” notation to address a different folder or the parent folder of the virtual folder structure on the Web server.

Full URLs are used to submit the form data to completely different Web site. For example, a Web site may embed an HTML form for newsletter subscription which submits its form fields to an external Web site, which provides email newsletter services.

To monitor the data exchanged between the current  page and the Web server, we use the Network tab. This tab is commonly used to confirm that resources are downloaded or uploaded correctly.

When you click on a link, the browser sends multiple requests to the server regarding different elements of the page. The HTML required to render the page is sent back in the form of responses from the server. There is information about every response that includes HTTP request URL, the request method, remote server IP address and port, status code and many other technical details.
