HTTP响应码1003是什么意思？

Question

Would anyone please tell me what does HTTP response code 1003 means. I tried googling it but unable to find a correct answer

Answer 1

HTTP redirect location does not exist

It is not a standard code but something used by Oracles crawler (?!)

Answer 2

Its a non-standard response code. Companies like Cloudflare use it to specify that the direct IP access is not allowed for this request.

I got this when i tried accessing 80 port of some IP which was a part of Cloudflare. But this does not mean that all 1003 responses mean the same. "Non Standard" :P

Answer 3

Multiple VMs hosted on the same IP address....fine but cloudy!
