Send Origin Header with websocket handshake

Not really sure where to put this, Kyatric would you kindly move this where appropriate,

Anyways, I'm coding a webserver in Golang that will hopefully handle websocket communication, and I think I hit a wall: the Origin Header is incorrect or not sent by the ws-plugin during the handshake, right now, I'm completely ignoring the Origin to make it work, but I'd love if Ashley confirmed that the header is sent properly by the websocket plugin

AFAIK the browser assigns the Origin header and it's not possible to change it from Javascript for security reasons. What exactly are you seeing with this header and is it consistent across browsers?

Ashley, I'm trying to start a websocket connection to my server from a localhost preview, but that server is giving me back, Error: Origin not allowed, is it because I'm running from localhost? I think so, I'll check when i have time to.

Nvm, It's on the server-side, and it's fixed

Probably CORS again, guessing you need to set Access-Control-Allow-Origin. (Guessing you figured this out but posting for searchers)

Ashley, yeah, I properly get the origin header but I don't handle it, so the connection closes abruptely
