The website I am developing requires authentication before you can access anything, but I want to allow users to share information with facebook once they have logged in. When I use the standard facebook sharer.php link it pulls up the data from the login page, not the page with the data the user would want to share.
http://www.facebook.com/sharer.php?u=<url to share>&t=<title of content>
Is there any way to allow Facebook to see the data behind the authentication?
