Understanding and Resolving CORS Error
· 5 min read
What is CORS and CORS preflight?
Cross-Origin Resource Sharing (CORS) is an HTTP-based security mechanism controlled and enforced by the client (web browser) that allows controlled access to resources located outside of a given domain.
Generally, for security reasons, browsers forbid requests that come in from cross-domain sources. However, there could be cases where you want to overcome this and access cross-domain resources, and CORS makes this possible.
