Cors...

Started new job at startup and finished all the development environment setup started development it was going smooth for one week.all the created API were working fine on the next day morning without any changes API's were giving cors error.asked my senior what must be the problem he said bypass cors and figure out the problem after trying for 1hrs i couldn't figure out what was the problem but API's were back to normal without any changes. then after sometime same day in zoom call i asked what was the problem he said show me the error but I couldn't reproduced the same cors error he then lectured me for 1 hrs and after that he said that learn to solve by your own dont come with silly mistake like this to me.
I don't know what was the problem he even refused me show to what the problem was.

CORS is shit
Stupid useless shit that protects from nothing. It is harmful mechanism that does nothing but randomly blocks browser from accessing resources - nothing more.

Main idea of CORS is that if server does not send proper header to OPTIONS request, browser will block other requests to that server.

What does stupid cocksuckers that invented CORS, think their retarded shit can protect from?
- If server is malicious, it will send any header required to let you access it.
- If client has malicious intents - he will never use your shit browser to make requests, he will use curl or any ther tool available. Also if server security bases on something as unreliable as http headers it sends to the client - its a shit server, and CORS will not save it.

Can anyone give REAL examples when CORS can really protect from anything?

Explain to me why CORS isn't the dumbest thing I've ever heard of?

I can make requests from outside the browser but not from within? Hah?

Is there any point in using cors without declaring the origin header?
