URL Frame (also known as URL masking or URL cloaking) is similar to URL Redirect, except that instead of redirecting the visitor to your web page, the web page is displayed in a frame from our web server. With this method, the visitor's browser will display your domain name (for example: www.mydomain.com) while they are using your site and not the actual URL to your page (for example: http://example.wordpress.com/2008/02/19/hello-world/).
