Hey Adam, You are very close. I think I’ll take this opportunity and possibly parts of your example (if you don’t mind) to beef up the dev-guide and of course help you along the way. The whole URL rewrite aspect is currently a large black hole. Can you show me the curl command you use “inside of the gateway” for your service that works? Username, passwords, hostnames and ports scrubbed to protect he innocent of course. ;) I’m most interested in the final URL required. Kevin.
