What are the differences between CORS and proxy servers?

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

Can you explain how CORS works in a web application?

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 indicating whether the request is permitted.

What are some common use cases for using a proxy server?

Common use cases for proxy servers include improving security, caching content to speed up access, bypassing geo-restrictions, and monitoring internet usage.

Are there any security risks associated with using proxies?

Yes, using proxies can introduce security risks such as data interception, especially if the proxy is not secure. It's important to use trusted proxy services.
