Class ContinuationFilter

java.lang.Object

org.eclipse.jetty.continuation.ContinuationFilter

All Implemented Interfaces:

javax.servlet.Filter

@Deprecated
public class ContinuationFilter
extends Object
implements javax.servlet.Filter

Deprecated.

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.
