// Function: HTTPChannel::reset
// Access: Published
// Description: Stops whatever file transaction is currently in
// progress, closes the connection, and resets to begin
// anew. You shouldn't ever need to call this, since
// the channel should be able to reset itself cleanly
// between requests, but it is provided in case you are
// an especially nervous type.
//
// Don't call this after every request unless you set
// set_persistent_connection() to false, since calling
// reset() rudely closes the connection regardless of
// whether we have told the server we intend to keep it
// open or not.
