SSL Complete Guide 2021: HTTP to HTTPS - Reverse Proxy and Cloudflare

The video tutorial explains Cloudflare as a global reverse proxy service that hides real web server IPs, uses caching to speed up content delivery, and saves bandwidth. It details how reverse proxies work, including DNS resolution and TCP session establishment. The benefits of reverse proxies, such as IP hiding, DoS attack prevention, and caching, are highlighted. Cloudflare's ability to serve content close to clients, reducing latency, is discussed. The tutorial concludes with Cloudflare's offer of free TLS certificates and a preview of the next steps in using Cloudflare.

What is one of the primary functions of Cloudflare as a reverse proxy?

• To eliminate the need for DNS servers

• To slow down content delivery

• To hide the IP address of real web servers

• To increase the number of web servers

In a reverse proxy setup, what does the web browser initially connect to?

• The DNS server

• The real web server

• The IP address of the client

• The reverse proxy

How does a reverse proxy help in reducing the load on web servers?

• By increasing the number of web pages

• By caching pages and serving them to multiple clients

• By eliminating the need for TCP sessions

• By directly connecting clients to the web server

What type of attacks can a reverse proxy help mitigate?

• Phishing attacks

• Denial of service attacks

• SQL injection attacks

• Cross-site scripting attacks

What happens to web pages after they are initially served by the web server in a reverse proxy setup?

• They are cached by the reverse proxy

• They are encrypted

• They are sent to the DNS server

• They are deleted from the server

What is a key advantage of using Cloudflare's global server network?

• It requires more DNS requests

• It limits the number of clients that can be served

• It reduces latency by serving content closer to clients

• It increases the cost of hosting

What is a significant benefit of Cloudflare's free plan?

• It offers unlimited bandwidth

• It guarantees 100% uptime

• It provides free TLS certificates

• It includes a dedicated server
