URL Whitelisting

Each Key can be whitelisted against a number of URLs. Individual Licensee Keys can have whitelisted URLs assigned to them.

Whitelisting works by matching the Referer and Origin headers of an incoming HTTP request against your list of whitelisted URLs. If no match has been found then a 4011 reply is returned.

If a matching URL is found, the request is allowed to proceed as normal. Furthermore, the Access-Control-Allow-Origin Response header is set as the requester's Origin header.

Whitelisting rules

Whitelisted strings beginning with http:// or https:// will look for matches that start with the string.

For instance, https://www.example.com will match https://www.example.com/ as well as https://www.example.com/signup.

Whitelisted strings which do not begin with http[s]:// will look for positive substring matches.

For instance, .example.com/signup will match https://www.example.com/signup as well as https://app.example.com/signup.
