XMLHttpRequest has a security model which is inadequate for supporting the next generation of web applications. JSONRequest is proposed as a new browser service that allows for two-way data exchange with any JSON data server without exposing users or organization to harm. It exchanges data between scripts on pages with JSON servers in the web. It is hoped that browser makers will build this feature into their products in order to enable the next advance in web application development.
This extension exposes JSONRequest to web pages. It has no visible user interface.
