Spring Cloud Zuul RateLimit

Module to enable rate limit per service in Netflix Zuul.
There are five built-in rate limit approaches:

• Authenticated User: Uses the authenticated username or 'anonymous'
• Request Origin: Uses the user origin request
• URL: Uses the request path of the upstream service
  • Can be combined with Authenticated User, Request Origin or both
• Authenticated User and Request Origin: Combines the authenticated user and the Request Origin
• Global configuration per service: This one doesn't validate the request Origin or the Authenticated User
  • To use this approach just don't set param 'type'
