CORS (Cross-Origin Resource Sharing) is a browser security feature that restricts web pages from making requests to a different domain than the one that served the web page. It's like having a bouncer at the door of your web app, checking IDs and deciding who gets in and who gets bounced.

How to use it in a sentence

• "I spent all day trying to debug this CORS (Cross-Origin Resource Sharing) error, only to realize I forgot to add the domain to the allowlist. Typical Monday."

• "Hey, did you hear about that new startup that got hacked because they misconfigured their CORS (Cross-Origin Resource Sharing) settings? Bet their investors are thrilled about that."
