Can you explain the concept of cross domain and how JSONP fits into the picture?

As a beginner in .net programming, I have created a webservice where JavaScript calls the webservice in my code. I attempted to call it using my phone's browser while on the same network. It works perfectly with localhost, but when trying to call the webservice method from another machine, it fails. Can you provide insight into why this is happening and if JSONP could potentially help resolve the issue?

Answer №1

Providing more information about the type of webservice you are attempting to call would greatly assist in finding a solution. Assuming it is RESTFUL, calling it from a different domain via XHR may not be successful due to the browser's Same origin policy. JSONP could potentially be the best alternative in this situation.

Additionally, exploring Cross-origin resource sharing (CORS) may be beneficial. This allows web servers to implement cross-site access controls.
