Method Detail

reset

public void reset()

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