What are the exceptions to the same-origin policy?

The same-origin policy restricts how documents or scripts from one origin can interact with resources from another origin. However, there are several exceptions, such as CORS (Cross-Origin Resource Sharing), which allows servers to specify who can access their resources.

Can you explain CORS in more detail?

Sure! CORS is a security feature that allows web applications to make requests to domains other than their own. It works by using HTTP headers to tell the browser whether to allow or deny the request based on the origin.

Are there any other exceptions besides CORS?

Yes, other exceptions include JSONP (JSON with Padding), which allows for cross-origin requests by using script tags, and certain HTML5 features like WebSockets that can bypass the same-origin policy.

What are the security implications of these exceptions?

While these exceptions enable greater flexibility for web applications, they can also introduce security risks, such as cross-site scripting (XSS) and data theft if not properly managed.
