Im interesting in how bookmarks work for social networks sites like facebook for example, when you look at someone's profile its
www.facebook.com/customname
or if they didnt make one yet its
www.facebook.com/generatedname
Is there a get request somewhere im missing??? Is the
www.facebook.com/profile.php?key=
hidden in the url? But how does the server know to interpret the url to look for someone's profile page? How does it work!!!!! Thanks!
Yes, the request is usually hidden using rewrite engines such as mod_rewrite.
As such something like facebook.com/customname is rewritten to facebook.com/profile.php?key=customname, which then internally looks up the correct profile page from the database.
