What is the protocol and host called?

Question

According to specification and semantics, the protocol and the host are combined: is https://example.comit still called the host, or is it called the URL, URI, or something else?

Also, (https) is called a protocol or scheme? NGINX uses the scheme , but I do not see any reference to this origin.

Actually, it's all on the wiki ... https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Relationship_between_URIs.2C_URLs.2C_and_URNs

Answer 3

( URI STD 66, RFC 3986.)

URI (, IP-) ( )

• scheme,
• :,
• //,
• authority
• path (→ path-abempty).

, https://example.com

• URI ( ),
• URI ( , /).

( URI , , , URI .)

HTTP RFC 2616 , URI HTTP: URI Request-URI (. ), URI abs_path , / (.. https://example.com/).

URI, HTTP , scheme authority.

IMHO, the origin is not the right term, because the origin refers to "where the message comes from." But it can also be a destination. Therefore, I believe that the base URL is the most suitable term for the protocol + host + port. See for example https://www.techopedia.com/definition/4858/base-url .
