All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class ProxyServlet
extends org.eclipse.jetty.proxy.ProxyServlet.Transparent

A transparent proxy servlet, which just forward http requests to the configured proxyTo server after stripping down the X_AUTH_HEADER token header. If you want to implement more sophisticated proxy routing logic, can do the same in rewriteTarget(HttpServletRequest) method.
