Comment:

 Here is a pull request for this ticket:
 https://github.com/cohosh/snowflake/pull/8.

 Even though we decided it wasn't strictly necessary, this puts all
 information in the body of the HTTP request/response. I think it's cleaner
 this way and we'll be using the same method for redoing the broker-client
 protocol eventually anyway.

 I opted for the "hard break" method of updating, since the worst case
 scenario is that a proxy that hasn't updated won't be able to usefully
 poll. As mentioned in #30704, web based proxies reboot themselves once a
 day. The standalone proxies will throw bad request error messages which
 should hopefully prompt those running them to update.
