TCP

TCP (Transmission Control Protocol) is currently one of the recommended transport protocols

It can be combined with various protocols in multiple ways.

TcpObject

TcpObject corresponds to the tcpSettings item in the Transport Protocol.

{
  "acceptProxyProtocol": false,
  "header": {
    "type": "none"
  }
}

acceptProxyProtocol: true | false

Only used for inbound, indicating whether to accept the PROXY protocol.

The PROXY protocol is used to transmit the real source IP and port of the request. If you are not familiar with it, please ignore this item.

Common reverse proxy software (such as HAProxy and Nginx) can be configured to send it, and VLESS fallbacks xver can also send it.

When filled in as true, after the underlying TCP connection is established, the requesting party must first send PROXY protocol v1 or v2, otherwise the connection will be closed.

The default value is false

header: NoneHeaderObject | HttpHeaderobject

Packet header obfuscation settings, the default value is NoneHeaderObject

::: tip HTTP obfuscation cannot be proxied by other HTTP servers (such as Nginx), but it can be proxied by VLESS fallbacks path. :::

NoneHeaderObject

No header obfuscation

{
  "type": "none"
}

type: "none"

Disable header obfuscation.

HttpHeaderObject

HTTP header obfuscation. The configuration must be the same between connecting inbound and outbound.

{
  "type": "http",
  "request": {},
  "response": {}
}

type: "http"

Enable HTTP header obfuscation.

request: HTTPRequestObject

HTTP request template.

response: HTTPResponseObject

HTTP response template.

Each request will include all the keys and randomly select a corresponding value. Please refer to the default values shown in the example above.
