About
Cross-Origin Resource Sharing (CORS) is an HTTP header-based mechanism used to safely bypass same-origin policy and allow requests to other domains.
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.
