 * **AllowedOrigins** `[]string`: A list of origins a cross-domain request can be executed from. If the special `*` value is present in the list, all origins will be allowed. An origin may contain a wildcard (`*`) to replace 0 or more characters (i.e.: `http://*.domain.com`). Usage of wildcards implies a small performance penality. Only one wildcard can be used per origin. The default value is `*`.
 * **AllowOriginFunc** `func (origin string) bool`: A custom function to validate the origin. It takes the origin as an argument and returns true if allowed, or false otherwise. If this option is set, the content of `AllowedOrigins` is ignored.
-* **AllowOriginRequestFunc** `func (r *http.Request origin string) bool`: A custom function to validate the origin. It takes the HTTP Request object and the origin as argument and returns true if allowed or false otherwise. If this option is set, the content of `AllowedOrigins` and `AllowOriginFunc` is ignored
+* **AllowOriginRequestFunc** `func (r *http.Request, origin string) bool`: A custom function to validate the origin.

 * **AllowedMethods** `[]string`: A list of methods the client is allowed to use with cross-domain requests. Default value is simple methods (`GET` and `POST`).
 * **AllowedHeaders** `[]string`: A list of non simple headers the client is allowed to use with cross-domain requests.
 * **ExposedHeaders** `[]string`: Indicates which headers are safe to expose to the API of a CORS API specification
