public class ProxyServlet
extends Object
implements Servlet

Asynchronous Proxy Servlet. Forward requests to another server either as a standard web proxy (as defined by RFC2616) or as a transparent proxy.

This servlet needs the jetty-util and jetty-client classes to be available to the web application.

To facilitate JMX monitoring, the "HttpClient", it's "ThreadPool" and the "Logger" are set as context attributes prefixed with "org.eclipse.jetty.servlets."+name (unless otherwise set with attrPrefix). This attribute prefix is also used for the logger name.

The following init parameters may be used to configure the servlet:

• name - Name of Proxy servlet (default: "ProxyServlet"
• maxThreads - maximum threads
• maxConnections - maximum connections per destination
