 **2. HTTP Video Request Authorization**
 
+In cases when your video request requires authorization, you can use the [`RequestAuthorizer`](https://github.com/arthur3486/ARVI/blob/master/arvi/src/main/java/com/arthurivanets/arvi/player/datasource/RequestAuthorizer.java) to provide the necessary auth token whenever the player requests it. The created [`RequestAuthorizer`](https://github.com/arthur3486/ARVI/blob/master/arvi/src/main/java/com/arthurivanets/arvi/player/datasource/RequestAuthorizer.java) should be passed around in the ARVI [`Config`](https://github.com/arthur3486/ARVI/blob/master/arvi/src/main/java/com/arthurivanets/arvi/Config.java) object.
