Web Proxies
===========

This section introduces various proxy types used to route web traffic through intermediate servers for purposes such as security, anonymity, or access control.

   * - Proxy Type
     - Description
     - Use Case
   * - HTTP Proxy
     - Intercepts and forwards HTTP requests between clients and servers.  
       *Supports caching and content filtering.*
     - Web traffic routing and access control.
   * - HTTPS Proxy
     - Similar to HTTP proxy but supports encrypted traffic (via `CONNECT` method).  
       *Ensures secure proxying for HTTPS traffic.*
     - Encrypted web access and secure inspection.
   * - SOCKS5 Proxy
     - General-purpose proxy that operates at Layer 5.  
       *Supports TCP/UDP and authentication.*
     - Torrenting, gaming, or bypassing restrictions.

   .. tab-item:: HTTP Proxy

      **RFC:** Based on HTTP/1.1 (RFC 7230)

      **Main Features:**

      - Forwards only HTTP traffic
      - Supports caching, content filtering, and access control
      - Easy to configure for web clients

      **Use Cases:**

      - Caching and logging web access
      - Restricting access to specific websites

      **Alternative Proxies:**

      - HTTPS – For secure connections
      - SOCKS5 – For general-purpose proxying

   .. tab-item:: HTTPS Proxy

      **RFC:** Uses HTTP `CONNECT` method (RFC 2817)

      **Main Features:**

      - Proxies encrypted HTTPS traffic
      - Enables SSL/TLS tunneling
      - Useful for secure inspection in enterprises

      **Use Cases:**

      - Secure browsing with access control
      - Logging encrypted sessions in corporate networks

      **Alternative Proxies:**

      - HTTP – For plain web traffic
      - SOCKS5 – For more flexible tunneling

   .. tab-item:: SOCKS5 Proxy

      **RFC:** RFC 1928

      **Main Features:**

      - Layer 5 proxy that supports both TCP and UDP
      - Authentication and flexible protocol support
      - No protocol-specific logic (unlike HTTP)

      **Use Cases:**

      - Torrenting, gaming, bypassing geo-blocks
      - Generic proxy support in many applications

      **Alternative Proxies:**

      - HTTP/HTTPS – Simpler for browsers
      - VPN – Encrypts and tunnels all traffic
