  Description copied from interface: Valve

  Perform request processing as required by this Valve.

  An individual Valve MAY perform the following actions, in the specified order:

  • Examine and/or modify the properties of the specified Request and Response.
  • Examine the properties of the specified Request, completely generate the corresponding Response, and return control to the caller.
  • Examine the properties of the specified Request and Response, wrap either or both of these objects to supplement their functionality, and pass them on.
  • If the corresponding Response was not generated (and control was not returned, call the next Valve in the pipeline (if there is one) by executing context.invokeNext().
  • Examine, but not modify, the properties of the resulting Response (which was created by a subsequently invoked Valve via a call to context.invokeNext()).

  A Valve MUST NOT do any of the following things:

  • Change request properties that have already been used to direct the flow of processing control for this request.
  • Create a completed Response AND pass this Request and Response on to the next Valve in the pipeline.
  • Consume bytes from the input stream associated with the Request, unless it is completely generating the response, or wrapping the request before passing it on.
  • Modify the HTTP headers included with the Response after the invokeNext() method has returned.
  • Perform any actions on the output stream associated with the specified Response after the invokeNext() method has returned.
