.
This method may elect not to pass the request to the next filter or
handler, and instead handle the request itself. It can achieve this by
merely avoiding a call to next.handle(context, request)
and creating its own response object. The filter is also at liberty to
replace a response with another of its own by intercepting the response
returned by the next handler.
