> Ironically, _Jetty_ has NO significance on the client, in a {{ClientCache}} application.
> Even when the application embeds a peer {{Cache}}, the server still might not require
_Jetty_.
> Jetty is only used to enable the embedded HTTP service in a GemFire server-side node
(e.g. Locator/Manager or Server).
> In the Manager, the embedded HTTP service implemented with _Jetty_ is used to host the
Management (Admin) REST API and Pulse.
> In a Server, the embedded HTTP service implemented with _Jetty_ is used to host the Developer
REST API.
> _Jetty_ should only be required when a server-side node (i.e. Locator/Manager or Server)
is hosting the Developer/Management REST API or Pulse.
> Please consider this change!
