[Serusers] handling failure after directing to application server

[Greg Martin]

I'm trying to direct requests to registered users to another proxy which has an application server. Right now the proxy simply sends a 404 back. In that case I want to simply complete the call. What I am doing is looping until the ser has had enough. I've tried to set a flag to prevent it but the
flag is in fact never set although the logs indicate it's the same transaction. Any comments?
