For example an Url http://www.hi-mama.com/forum/ or more of UrlWhat you want exactly?? i don't understand if u want to hide a link in a Rich Text object, html or in source code... be more specific please
Sorry but i cant help u with this, u can read a webpage in IE object but always can get the url with properties.
You can use IEXPLORER plugin, and make a check code in OnNavigate event, one of its params it's the full url accessed, so you can regexp or explode the url and check wath you want
