Class IncludableGzipFilter

java.lang.Object

org.eclipse.jetty.servlets.UserAgentFilter

org.eclipse.jetty.servlets.GzipFilter

org.eclipse.jetty.servlets.IncludableGzipFilter

All Implemented Interfaces:

javax.servlet.Filter

public class IncludableGzipFilter
extends GzipFilter

Includable GZip Filter. This extension to the GzipFilter that uses Jetty features to allow headers to be set during calls to RequestDispatcher.include(javax.servlet.ServletRequest, javax.servlet.ServletResponse). This allows the gzip filter to function correct during includes and to make a decision to gzip or not at the time the buffer fills and on the basis of all response headers. If the init parameter "uncheckedPrintWriter" is set to "true", then the PrintWriter used by the wrapped getWriter will be UncheckedPrintWriter.
