At the moment, it is only possible to evaluate a target based on credentials.

It would be cool to be able to evaluate also based on request information, such as remote address or domain.

The following words are prefixes that can be used for matching information:

• credentials - Information from request.auth.credentials object. Information in this object depends on your authentication implementation.
• connection - Connection information, from request.info, as documented in hapi:
  • connection:host - Content of the HTTP 'Host' header (e.g. 'example.com:8080').
  • connection:hostname - The hostname part of the 'Host' header (e.g. 'example.com').
  • connection:received - Request reception timestamp.
  • connection:referrer - Content of the HTTP 'Referrer' (or 'Referer') header.
  • connection:remoteAddress - Remote client IP address.
  • connection:remotePort - Remote client port.
• query - Query parameters, as in request.query.
• param - URL parameters, as in request.params.
• request - Other request information:
  • request:path - Requested path.
  • request.method - Requested method (e.g. post).
