Method Detail

reset

public void reset()

It is possible to re-send the response of an already handled request (by a servlet) as a new request object. The new response will then be added (at the end) of the first response, if -for some reason- the (new) response alone should be send to the client. In this case the response stream must be reset before it is sent to the client anew. This is what this method is for.
