Class ProxyServlet.Transparent

java.lang.Object
  org.mortbay.servlet.ProxyServlet
      org.mortbay.servlet.ProxyServlet.Transparent

All Implemented Interfaces:

Servlet

Enclosing class:

ProxyServlet

public static class ProxyServlet.Transparent
extends ProxyServlet

Transparent Proxy. This convenience extension to AsyncProxyServlet configures the servlet as a transparent proxy. The servlet is configured with init parameter:

• ProxyTo - a URI like http://host:80/context to which the request is proxied.
• Prefix - a URI prefix that is striped from the start of the forwarded URI.

For example, if a request was received at /foo/bar and the ProxyTo was http://host:80/context and the Prefix was /foo, then the request would be proxied to http://host:80/context/bar
