terminology - What do you call the entire first part of a URL?

Question

If I have a URL like:

http://www.example.com:9090/test.html

Then I know that www.example.com is the host name, but what do you call http://www.example.com:9090? Is there some kind of established name for that?

Answer 1

It is called the origin.

More generally speaking, here are the different parts of a URL, as per window.location. (So at least according to how Javascript calls it)

protocol://username:password@hostname:port/pathname?search#hash
-----------------------------href------------------------------
                             -----host----
-----------      origin      -------------

• protocol - protocol scheme of the URL, including the final ':'
• hostname - domain name
• port - port number
• pathname - /pathname
• search - ?parameters
• hash - #fragment_identifier
• username - username specified before the domain name
• password - password specified before the domain name
• href - the entire URL
• origin - protocol://hostname:port
• host - hostname:port

Formal definition is in RFC 6454 section 4.
