/**
* Implemented for bug 79865
*
* <p>Disable the Jetty timeout for for this request.
*
* <p>By default (and our normal configuration) Jetty has a 60 second idle timeout (10 if the
* server is busy) for connection endpoints. There's another task that keeps track of what
* connections have timeouts and periodically works over a queue and closes endpoints that have
* been timed out. This plays havoc with DAV over slow connections and whenever we have a long
* pause.
