It essentially transmits all you throw in internet marketing for your localhost. Can you really do that with apache server and .htaccess? It is also things i used like a callback url after i was developing using twitter's API. So I am curious.


There's no HTTP server involved here whatsoever. The DNS An archive for is 127...1, which describes your personal machine.

By using their title like a "callback url" most likely will not work on all, for how long Twitter attempts to contact, they'll get 127...1, which describes their own machine (not yours).
