In terms of client traffic support, how do ZTunnel 1.0 and ZTunnel 2.0 differ?

ZTunnel 1.0 employs the HTTP CONNECT method to establish a tunnel for client traffic. This technique is commonly used by various proxy servers to facilitate tunneling of requests over HTTP. When a client wants to connect to a server, it sends an HTTP CONNECT request, and if the server and the proxy accept the connection, it can then tunnel the TCP connection through that HTTP session.

The significance of the HTTP CONNECT method lies in its ability to support applications that require TCP connectivity, such as web browsers using HTTPS. ZTunnel 2.0 enhances this functionality by providing broader support for protocols and increased performance and security features, but ZTunnel 1.0's reliance on the HTTP CONNECT method is a defining characteristic that allows for effective management of client traffic in specific scenarios.

In contrast, the other choices don't accurately represent the characteristics of ZTunnel 1.0. For example, while ZTunnel 1.0 does indeed handle certain types of traffic, it does not support all client traffic the same way ZTunnel 2.0 does. Furthermore, ZTunnel 1.0 does not utilize DTLS; that is a feature of later iterations. Similarly, while mobile devices can connect using ZTunnel 1.0, this
