Class ProxyServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.pentaho.platform.web.servlet.ServletBase
              org.pentaho.platform.web.servlet.ProxyServlet

All Implemented Interfaces:

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

public class ProxyServlet
extends ServletBase

This servlet is used to Proxy a Servlet request to another server for processing and returns that result to the caller as if this Servlet actiually serviced it. Setup the proxy by editing the web.xml to map the servlet name you want to proxy to the Proxy Servlet class.

  <servlet>
    <servlet-name>ViewAction</servlet-name> 
    <servlet-class>com.pentaho.ui.servlet.ProxyServlet</servlet-class>
    <init-param>
       <param-name>ProxyURL</param-name>
       <param-value>http://my.remoteserver.com:8080/pentaho</param-value>
    </init-param>
   </servlet>
 

In the above example, all requests to /ViewAction will be forwarded to the ViewAction Servlet running on the Pentaho server atmy.remoteserver.com:8080

NOTES:

For this to be useful, both Pentaho servers should be using the same database repository.

The recieving server should have the ProxyTrustingFilter enabled to handle authicentation.

This Servlet only works with GET requests. All requests in the Pentaho BI Platform are currently gets.
