public class BufferedResponseHandler
extends HandlerWrapper

Buffered Response Handler

A Handler that can apply a HttpOutput.Interceptor mechanism to buffer the entire response content until the output is closed. This allows the commit to be delayed until the response is complete and thus headers and response status can be changed while writing the body.

Note that the decision to buffer is influenced by the headers and status at the first write, and thus subsequent changes to those headers will not influence the decision to buffer or not.

Note also that there are no memory limits to the size of the buffer, thus this handler can represent an unbounded memory commitment if the content generated can also be unbounded.

handle

public void handle(java.lang.String target,
                   Request baseRequest,
                   javax.servlet.http.HttpServletRequest request,
                   javax.servlet.http.HttpServletResponse response)
            throws java.io.IOException,
                   javax.servlet.ServletException

Description copied from interface: Handler

Handle a request.

Specified by:

handle in interface Handler

Overrides:

handle in class HandlerWrapper

Parameters:

target - The target of the request - either a URI or a name.

baseRequest - The original unwrapped request object.

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

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