  "title": "HTTP/2 Protocol Implementation Steps",
  "steps": [
    {
      "stepNumber": 1,
      "title": "Establish a Transport Layer Security (TLS) Connection",
      "details": "This is the first step to ensure secure communication between the client and the server using TLS 1.2 or higher, which enables the ALPN (Application Layer Protocol Negotiation) to announce HTTP/2 support."
    },
    {
      "stepNumber": 2,
      "title": "Negotiate HTTP/2 Protocol Using ALPN",
      "details": "During the TLS handshake, the client and server exchange supported protocols. If the server supports HTTP/2, it chooses it through ALPN. This step ensures that both parties have agreed to use HTTP/2."
    },
    {
      "stepNumber": 3,
      "title": "Initialize HTTP/2 Connection",
      "details": "The client sends a connection preface (PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n) followed by a SETTINGS frame to the server. The server responds with its own SETTINGS frame to initialize the HTTP/2 session."
    },
    {
      "stepNumber": 4,
      "title": "Exchange of Frames",
      "details": "Data is exchanged between the client and server in the form of frames. Frames can be of various types such as HEADERS, DATA, and PRIORITY, each serving specific purposes like sending headers, payload data, and defining frame priorities."
    },
    {
      "stepNumber": 5,
      "title": "Multiplexing of Streams",
      "details": "HTTP/2 allows multiple streams of data to be sent concurrently over a single TCP connection. Each stream has a unique identifier and can be prioritized based on the PRIORITY frames exchanged during the session."
    },
    {
      "stepNumber": 6,
      "title": "Flow Control",
      "details": "To manage the flow of data between client and server, WINDOW_UPDATE frames are used. These frames adjust the window sizes that control how much data can be sent and received without being acknowledged."
    },
    {
      "stepNumber": 7,
      "title": "Server Push",
      "details": "The server can initiate responses to a client's request by pushing additional resources, specified in PUSH_PROMISE frames, which are used to inform the client of future responses."
    },
    {
      "stepNumber": 8,
      "title": "Connection Termination",
      "details": "The session can be terminated by sending a GOAWAY frame from either the client or server, which indicates that the connection is being shut down and specifies an error code if the connection did not end normally."
    }
