com.helger.servlet.http.CountingOnlyHttpServletResponse

All Implemented Interfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class CountingOnlyHttpServletResponse
extends javax.servlet.http.HttpServletResponseWrapper

A response that includes no body, for use in (dumb) "HEAD" support. This just swallows that body, counting the bytes in order to set the content length appropriately. All other methods delegate directly to the wrapped HTTP Servlet Response object.

Since:

8.8.0

Author:

Servlet Spec 3.1
