 ## Advanced features
 
-### Using EnQueueToken
-A token could be used for queueing the users. This makes it even more protected. The token will be included when the user is redirected from Akamai to the queue and vice versa. [QueueToken](https://github.com/queueit/QueueToken.V1.JavaScript) package has been used to generate this token. The generated token will be valid for 1 minute.
+### Ignoring OPTIONS requests
+If you want to ignore all HTTP OPTIONS request, ex. no triggers will be evaluated, it can be achieved with a global setting.
+- Add a variable with name PMUSER_QUEUEIT_IGNORE_OPTIONS_REQUESTS and value 'true' to your Akamai property.
 
-To use the EnqueueToken follow the below steps:
-- The waiting room should be configured to accept this token. This configuration could be made in Queue-it Go platform.
-- SHOULD_INCLUDE_ENQUEUETOKEN variable should be set to ```true``` in the ```main.js``` file.

+[QueueToken](https://github.com/queueit/QueueToken.V1.JavaScript) package has been used to generate this token. The generated token will be valid for 1 minute.
