Capabilities of Httpobject within T2D?

Im curious, the httpobject, does this simply send a request to a webpage? any webpage?
does the object bring something back if the page produces it? ie the results of the page? and if the results are a sting of variables, how is this accessable in torque?

Also
If i stored usernames/passwords with the client and worked my authentication using either application or session variables, could i run an infomation server using asp/sql server (my forte)

If so
Im thinking then i would be sending the username and password across with every single request? because i wouldnt have the localised cookie capability that allow IE or other browsers to store the info for the server to pick up.

Effectively what would be possible here is the running of a massive network game (based on web server capabilities) if i was intending the game to be tick based or turn based, real time being a bit of a problem.

Sorry if im a bit behind with this concept but i wasnt aware that T2D even touched on this.

If my question is unclear, basically are the capabilities/functionality of httpobject? ie how it works, what it does and how the results it finds are handled.
