Sec-WebSocket-Key should be base64 encoded instead of UUID string
Created by: vanwinkeljan
The websocket client implementation sends the generated UUID as a string instead of base64 encoded
RFC 6455 - 4.1. Client Requirements
- The request MUST include a header field with the name |Sec-WebSocket-Key|. The value of this header field MUST be a nonce consisting of a randomly selected 16-byte value that has been base64-encoded (see Section 4 of [RFC4648]). The nonce MUST be selected randomly for each connection.
