Class ProxyFilter

java.lang.Object

org.opennms.container.web.bridge.proxy.ProxyFilter

All Implemented Interfaces:

javax.servlet.Filter, RequestHandlerRegistry

public class ProxyFilter
extends Object
implements javax.servlet.Filter, RequestHandlerRegistry

The Apache Felix Http Bridge requires a Http Proxy on the SErvlet Container (Jetty) Side in order to work properly. The default implementation uses the ProxyServlet. However, this only forwards requests to a certain context, e.g. /osgi. This breaks with a lot of components, e.g. Vaadin is required to be exposed to /VAADIN In order to compensate, a Filter is used instead, which forwards to the HttpServlet of the Apache Felix Http Bridge. To only forward/dispatch requests which can actually be handled by OSGi-registered Servlets, all registered Servlet's are persisted here.
