I have a webapp that runs within a jetty servlet.
When it starts, it runs on localhost:8888/
I'm using a separate Ruby / Sinatra process to manage my assets (js, css, images). This runs on localhost:3000/
Ideally, I would like a Jetty ProxyServlet that sends any requests from localhost:8888/assets/* to localhost:3000/assets/* as to avoid cross-domain errors.
This is only in development, my production assets will be served elsewhere so don't answer in the context of scalability or other concerns.
Also, I would need these two "Servlets" to run sidebyside within the same PORT 8888?
So again... All requests to localhost:8888/* (except, /assets/) would route to the main webapp servlet. All requests to localhost:8888/assets/ would route to the ruby / sinatra server localhost:3000/assets/*

I was thinking something like this?
But it just causes 503 Service Unavailable
<servlet>
<servlet-name>JettyProxy</servlet-name>
<servlet-class>org.mortbay.servlet.ProxyServlet$Transparent</servlet-class>
<init-param>
<!-- This points to the actual server where requests are proxied to -->
<param-name>ProxyTo</param-name>
<param-value>http://localhost:3000/</param-value>
</init-param>
<init-param>
<!-- This will be stripped off the client request URL -->
<param-name>Prefix</param-name>
<param-value>/</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JettyProxy</servlet-name>
<url-pattern>/assets/*</url-pattern>
</servlet-mapping>
Is this possible? If so, how would it be implemented?
Your tag says you are using jetty-8 but your proxy servlet class indicates jetty-6 (the org.mortbay.servlet.ProxyServlet). On jetty-8 the ProxyServlet you should be using is org.eclipse.jetty.servlets.ProxyServlet and yes, this all sounds like a perfectly normal use case.
