stateful - HTTP/2 的哪些部分是有状态的？

Question

与最初的无状态 HTTP/1 不同，HTTP/2有许多有状态的组件。
HTTP/2 的这些部分是有状态的:

Header blocks refer to a stateful unsigned 31-bit integer called a stream identifier

Frames also reference the same stateful stream identifier

opportunistic encryption also depends on state since TLS is stateful
