Unblock-Youku is a geo-blocking circumvention tool and proxy server designed to grant access to region-locked video streaming and web services. It functions as a regional content unblocker that masks a user's location to bypass geographic restrictions.
The system operates as an SNI proxy server, forwarding HTTPS traffic based on the Server Name Indication without decrypting the payload. It also serves as a transparent proxy gateway and a DNS-based request router that directs network traffic to specific proxy servers by modifying name resolution records for regional domains.
Its capabilities cover DNS request routing, SNI proxy forwarding, and the redirection of traffic to overcome regional playback errors and location blocks. It utilizes domain-specific traffic splitting and HTTP proxy tunneling to facilitate regional content access.
