  • Upstream: A group of backend servers used for load balancing.
Common CLI Commands

Understanding Nginx
Reverse Proxy vs Load Balancer

A Reverse Proxy sits in front of your web servers and forwards client requests to those web servers. A Load Balancer distributes incoming network traffic across a group of backend servers to ensure no single server bears too much load.

Security Headers Explained
  • HSTS: Tells browsers to only access the site via HTTPS.
  • X-Frame-Options: Prevents your site from being embedded in iframes (clickjacking protection).
  • CSP: Controls which resources the user agent is allowed to load for a given page.
