face book share external url
I have a addthis button that shares the urls of my wesite as well as external website urls .I had done all the meta tag configuration for the facebook (http://support.addthis.com/customer/portal/articles/381222-optimize-facebook-sharing#.T-BiZIwtgwk). Now my facebook sharing with my website page is working perfectly , fetching image , description , and url . is there any way to make the external url sharing to display my website logo and description .I read facebook scraps the given url conaten and display the shared content , but is their any option to override this while sharing external url?
