handle

public void handle(java.lang.String path,
                   Request baseRequest,
                   HttpServletRequest request,
                   HttpServletResponse response)
            throws java.io.IOException,

request - The request either as the Request object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getRequest() method can be used access the Request object if required.

response - The response as the Response object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getResponse() method can be used access the Response object if required.

Throws:

java.io.IOException - if unable to handle the request or response processing

ServletException - if unable to handle the request or response due to underlying servlet issue
