In most web frameworks (ASP, PHP, JSP, ASP.NET WebForms, etc), incoming URLs typically map to template files stored on disk. For example, a "/Products.aspx" or "/Products.php" URL typically has an underlying Products.aspx or Products.php template file on disk that handles processing it. When a http request for a web application comes into the web server, the web framework runs code specified by the template file on disk, and this code then owns handling the processing of the request. Often this code uses the HTML markup within the Products.aspx or Products.php file to help with generating the response sent back to the client. |
