Q5

Compare Forward Proxy and Reverse Proxy.

💬Answer
  • Forward Proxy: Acts on behalf of clients to filter, cache, or anonymize outgoing internet requests (e.g., a corporate firewall blocking employees from accessing social media).
  • Reverse Proxy: Acts on behalf of servers. It intercepts incoming requests from the internet and forwards them to internal backend servers (e.g., Nginx handling SSL termination, IP masking, and static caching).
    • Key Functions:
      • Load Balancing: Distributes incoming HTTP requests to healthy backend application instances.
      • Security (IP Masking): Hides the IP address of backend servers from clients, preventing direct exploitation.
      • SSL/TLS Termination: Handles decryption of HTTPS traffic, reducing CPU load on backend servers.
      • Caching: Caches static assets (images, CSS, JS) locally to speed up user load times.
      • Common Example: Nginx is widely used as a reverse proxy, web server, and API gateway.
