additional_querylist

The 'additional_querylist' directive is part of the Secure Token module for NGINX, which is designed to generate content delivery network (CDN) tokens that protect media files in streaming scenarios. This directive specifically enables users to append additional query parameters to the tokens generated by the module. By providing a way to include extra parameters in the secure token, users can enhance access control and extend the capabilities of their streaming setups.

In practice, when configuring this directive, the user specifies one or more query parameters that should be included alongside the default secure token parameters, such as expiration time and access control lists (ACLs). This added flexibility is critical for scenarios where additional context or metadata is required for content delivery. The directive expects a single argument that defines the list of additional query parameters to include in the secure token string.
