Accepting the very likely risk that I have not a clue what I'm talking
about other than the fact I recently ran into this on our website, may I
humbly suggest the following:

If HTTP is being used as the transport, including the following HTTP
headers is supposedly your best bet for keeping any and all endpoints
and intermediaries from caching data that comes their way:

  Expires: -1
  Cache-Control: no-store, no-cache, must-revalidate   // HTTP/1.1
  Cache-Control: post-check=0, pre-check=0
  Pragma: no-cache                                     // HTTP/1.0

I hope this helps, but as I said earlier, your mileage may (greatly)
