What is Proxy Server

 A proxy server acts as an intermediary between a client and a server. It processes requests and responses, allowing for added functionality such as anonymity, caching, or access control.

Key Functions of a Proxy Server:

1. Anonymity:
   • Hides the client's IP address from the server.
   • Provides an additional layer of privacy for the user.
2. Caching:
   • Stores frequently accessed resources locally.
   • Reduces load times and server bandwidth usage.
3. Access Control:
   • Filters requests based on IP, domain, or protocol.
   • Restricts access to certain websites or services.
4. Content Filtering:
   • Blocks inappropriate or malicious content.
   • Enforces organizational policies on browsing behavior.
5. Traffic Monitoring:
   • Tracks and logs usage for auditing purposes.
   • Helps identify unusual or unauthorized activity.
6. Bypassing Restrictions:
   • Allows access to region-restricted content.
   • Circumvents firewalls and network restrictions.

Types of Proxy Servers:

1. Forward Proxy:
   • Sits in front of clients and forwards requests to servers.
   • Commonly used for internet access control or filtering.
2. Reverse Proxy:
   • Sits in front of servers and handles client requests on their behalf.
   • Enhances load balancing, security, and caching.
3. Transparent Proxy:
   • Doesn't modify requests or responses; users may not know it's present.
   • Often used for monitoring purposes.
4. Anonymous Proxy:
   • Hides the client's IP address but identifies itself as a proxy.
   • Offers privacy without complete anonymity.
5. High Anonymity Proxy:
   • Hides the client's IP and doesn't reveal that it is a proxy.
   • Provides maximum anonymity.
