in the context of websockets is the UPGRADE request redundant now?
https://developer.mozilla.org/en-US/docs/Web/HTTP/Protocol_upgrade_mechanism#upgrading_to_a_websocket_connection
i was interested in using the base web sockets and going through the motions of implementing this protocol but after reading more about it, it seems that it already occurs in the websocket api, so its not necessary to do myself?
If I did want to do websockets from scratch, where would I start outside the websocket api?
Protocol upgrade mechanism - HTTP | MDN
The HTTP/1.1 protocol provides a special mechanism that can be used to upgrade an already established connection to a different protocol, using the Upgrade header field.
