public class ContinuationFilter extends Object implements javax.servlet.Filter
ContinuationFilter must be applied to servlet paths that make use of
the asynchronous features provided by Continuation APIs, but that
are deployed in servlet containers that are neither Jetty (>= 7) nor a
compliant Servlet 3.0 container.
The following init parameters may be used to configure the filter (these are mostly for testing):
If the servlet container is not Jetty (either 6 or 7) nor a Servlet 3 container, then "faux" continuations will be used.
Faux continuations will just put the thread that called Continuation.suspend()
in wait, and will notify that thread when Continuation.resume() or
Continuation.complete() is called.
Faux continuations are not threadless continuations (they are "faux" - fake - for this reason) and as such they will scale less than proper continuations.
