What is the difference between CORS and a proxy?

CORS, or Cross-Origin Resource Sharing, is a security feature that allows or restricts resources requested from another domain. A proxy, on the other hand, acts as an intermediary for requests from clients seeking resources from other servers.

Can you explain how CORS works?

Sure! CORS works by using HTTP headers to tell the browser whether to allow or deny requests from different origins. When a web application makes a request to a different domain, the server can respond with specific headers to indicate if the request is permitted.

What are some common use cases for using a proxy?

Proxies are commonly used for various purposes, such as improving security, caching content, bypassing geo-restrictions, and load balancing requests.

Are there any security concerns with using proxies?

Yes, using proxies can introduce security risks, such as data interception or exposure to malicious proxies. It's important to use trusted proxy services.
