Is a decorated URL  a better option ?

IMHO the best way would to use SSL connections to reduce sniffing. If you
can support client certificates you can use them as well but don't rely on
them purely.

Once you have an encrypted tunnel use user authentication with hardware
tokens like Shiva Access Manager or Ace's Secure Server. (Combine username
+ user password with pin and hardware token reponse for authentication.)

Then you can use cookies to cache the use info for a limited time. (Don't
push it over an hour and make sure you keep them rather secure.)

Beside the client certificates this is how I did create a support server.
