    use Servlet 3.0 AsyncContext instead

    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 a compliant Servlet 3.0 container.

    The following init parameters may be used to configure the filter (these are mostly for testing):

    debug
    Boolean controlling debug output
    faux
    Boolean to force use of faux continuations

    If the servlet container is not Jetty 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.
