Simple component lets you hide links (e.g. hide affiliate links). It is sometimes necessary to hide, or cloak, your affiliate links to stop people stealing your commission or bypassing the affiliate link and going straight to the main site. This component frames the site you are promoting making it looks to the visitor as if they are still on your site. In other words, no matter which page they go to on the framed site they will only see your own domain in the browser window - Hide link servlet
For JSP you can use Mask URL taglib for the same purpose.
