Web Browser's Same-origin Policy Scenarios

What is the same-origin policy enforced by web browsers?

Choose the scenario that is NOT against a web browser's same-origin policy:

A. Sending an AJAX request from this page to A

B. Sending an AJAX request from this page to B

C. Sending an AJAX request from this page to C

D. Sending an AJAX request from this page to D

E. None of the above.

Answer:

Final answer: Sending an AJAX request from this page to B is NOT against a web browser's same-origin policy.

The same-origin policy is a security concept enforced by web browsers to prevent scripts from one origin (domain) from accessing resources on a different origin. Two URLs have the same origin if they have the same protocol, host, and port number.

In this case, since both A and C have the same origin as the current page, sending an AJAX request to A or C does not violate the same-origin policy. However, sending an AJAX request to B from the current page would violate the same-origin policy.

By adhering to the same-origin policy, web browsers help protect user data and enhance security while browsing the internet.
