What technology Facebook uses for links?
Just wanted to know what technology facebook uses while posting links. I have noticed that whenever i paste a link on screen, i get the link as a page.
For example,when i paste youtube's link... it displays as a video and i can play it there only.
Can some one please let me know how it can be done. what all is needed
