It seems that the load balancer is really rewriting redirects:

(src/java/com/wyona/tomcat/cluster/proxy/HttpProxy.java)

    private void rewriteResponseHeaders(HttpServletResponse 
servletResponse, HttpMethod method, RequestStatus status) {
        switch (status.getStatusCode()) {
            case HttpStatus.SC_MOVED_PERMANENTLY:
            case HttpStatus.SC_MOVED_TEMPORARILY:
                rewriteLocation(servletResponse, method);
            break;
        }
    }


but it's strange, because it should only rewrite 302 reponses and not 
301 ...

Also I don't understand why it actually rewrites just one of them ...

Will debug some more ;-)

Cheers

Michi
