Facebook application using joomla

hi, i have developed a facebook application using joomla, it's a web site included in canvas page so i need to hide real domain of web application and allow acces just from facebook. i tried to do this modifing htaccess file but it's not the solution because starts a including loop. i think best thing would be use a redirect (php or javascript) following simple rule redirect domainapplication.com/page1 to https;//apps.facebook.com/applicationname/page1. i need to do this in a dynamic way not page for pgae. maybe would be great provide this features in next release of jfbconnect, tx
