Question

I am trying to use the transparent proxy provided by jetty.

This is my web.xml

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" id="WebApp_9"
     version="2.4"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<display-name>Archetype Created Web Application</display-name>

<servlet>
    <servlet-name>googleProxy</servlet-name>
    <servlet-class>org.eclipse.jetty.servlets.ProxyServlet$Transparent</servlet-class>
    <init-param>
        <param-name>ProxyTo</param-name>
        <param-value>http://www.google.com</param-value>
    </init-param>
    <init-param>
        <param-name>Prefix</param-name>
        <param-value>/google</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>googleProxy</servlet-name>
    <url-pattern>/google/*</url-pattern>
</servlet-mapping>

and this is the pom.xml (I am using maven):

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                        <goal>stop</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

I expect the proxy to forward a request like this:

http://localhost:8080/JettyProxySample/google/search?q=hello

to this:

http://www.google.com/search?q=hello

But when I try that url in browser, I always get this:

HTTP ERROR: 403

FORBIDDEN
RequestURI=/JettyProxySample/google/search

Powered by Jetty://

Any idea?

Just to toss an answer onto here, do not use a milestone release that is years old.

• 7.6.7.v20120910 for jetty7
• 8.1.7.v20120910 for jetty8

I know lots of folks using the proxy servlet in both versions successfully, just not something that was from the initial migrations from codehaus to eclipse…there was a serious amount of code churn back then so I would not be surprised if this isn’t working correctly for you.
