Controls the permissions for .m3u8 and .ts fragment resources.
Implements custom access control based on the Referer request header.
Forwards the request to a specified remote authentication server. Allows access if the validation is passed and denies if not.
Uses the Web Crypto API to implement HMAC-SHA256 signature and stores the signature information in the request header, to complete data integrity check or identity authentication in cooperation with the origin server.
Implement complex URL rewrite functionality, including path replacement based on Regex and path case normalization.
