cors general & browser infos

cors (Cross-origin resource sharing)

info

cors en wiki

Certain "cross-domain" requests, notably Ajax requests, are forbidden by default by the same-origin security policy. CORS defines a way in which a browser and server can interact to determine whether it is safe to allow the cross-origin request.[3] It allows for more freedom and functionality than purely same-origin requests, but is more secure than simply allowing all cross-origin requests.
