HTTP/2 specific headers

Question

Where can I find a complete guide of http2 specific headers (:method :status :path etc..)

There's nothing on MDN, I found articles what describe HTTP/2 protocol but cannot find a complete list of these headers

Answer 1

These are defined in the HTTP/2 RFC specification: https://www.rfc-editor.org/rfc/rfc7540

And in particular on sections 8.1.2.1 which defines what they are:

While HTTP/1.x used the message start-line (see [RFC7230], Section 3.1) to convey the target URI, the method of the request, and the status code for the response, HTTP/2 uses special pseudo-header fields beginning with ':' character (ASCII 0x3a) for this purpose.

Pseudo-header fields are not HTTP header fields. Endpoints MUST NOT generate pseudo-header fields other than those defined in this document.

And in Sections 8.1.2.3 and 8.1.2.4 which defines the request and response pseudo headers respectively and lists them as follows:

Request

• :method
• :scheme
• :authority
• :path

Response

• :status
