JSONP Pronunciation

JSONP Description

JSONP (JSON with padding) is used to request data from a server residing in a different domain than the client. It was proposed by Bob Ippolito in 2005. JSONP enables sharing of data bypassing same-origin policy. The policy disallows running JavaScript to read media DOM elements or XHR data fetched from outside the page's origin. The aggregation of the site's scheme, port number and host name identifies as its origin. Due to inherent insecurities, JSONP is being replaced by CORS.
