/* prim-dns v2.5.0
*
* The prim-dns server script is a modular SecondLife script that will request
* a temporary URL and register that URL with a prim-dns web service instance
* to automatically create a permanent alias, which client scripts can use to
* find the current temporary URL of the server at any given time. This allows
* you to quickly add robust HTTP server functionality to any prim, and the
* modular design means the core script can be updated without needing to edit
* your own code, and different functions of a server can be split across
* multiple scripts for easier management.
