About

The Content-Security-Policy (CSP) HTTP response header and HTML meta tag define which external websites a web page can load content from.

They help prevent attacks such as cross-site scripting (XSS) and data injection by blocking content from untrusted sources.

The ETag HTTP response header is an identifier for a specific version of a resource that is used for cache validation.

It enables browsers to verify whether a cached resource is still up to date by sending the ETag back to the server, which compares it with the current version and returns the resource only if it has changed.
