Well you need to search after mod_rewrite it allows to rewrite URLS to another url like the facebook one.

More information on the apache site: http://httpd.apache.org/docs/current/mod/mod_rewrite.html

You need a .htaccess file with mod_rewrite rules (tutorial) that pushes those requests to a .php file. There you can look at the original request, and fetch the user details.
