[FIXED] Why Jetty asks for ProxyTo, when I have provided one

Issue

I have code for starting a web app in Jetty. I want to add reverse proxy handling inside the app. When I call API,

I get error UnavailableException: Init parameter 'proxyTo' is required.

Server server = new Server(port);

WebAppContext webapp = createWebAppContext();

ServletHolder proxyServlet = new ServletHolder(ProxyServlet.Transparent.class);
proxyServlet.setInitParameter("ProxyTo", "http://attachments.dev.balcia.com:30310/api/");
proxyServlet.setInitParameter("Prefix", "/api");
webapp.addServlet(proxyServlet, "/api/attachments/*");

server.setHandler(webapp);

Solution

The init-parameter is called proxyTo not ProxyTo.

Servlet init-parameters are case sensitive.
