# The Role of Proxy Servers

#### Definition and Principles of Proxy Servers

A proxy server is a server located between the user and the internet, acting as an intermediary layer that processes user requests and forwards them to the internet, protecting client privacy and improving access speed. The working principle of a proxy server mainly includes receiving user requests, forwarding requests, obtaining responses, and returning them to the user. Through a proxy server, functions such as caching, filtering, and load balancing can be realized.

Different types of proxy servers are divided into forward proxies and reverse proxies. A forward proxy is located between the client and the target server, representing the client to request resources from the target server; a reverse proxy is located between the target server and the client, representing the server to provide services to the client. In addition, anonymous proxies hide the client's real IP address, while transparent proxies do not hide it and directly pass the client's IP to the server.

#### Differences Between Forward Proxies and Reverse Proxies

| Feature | Forward Proxy | Reverse Proxy |
|---------------|-----------------------------------------|----------------------------------------|
| Location | Located between the client and target server | Located between the target server and client |
| Function | Represents the client to access the target server | Represents the target server to provide services to the client |
| Privacy Protection | Can hide the client's real IP address | Does not hide the client IP, passes it to the target server |
| Usage | To break access restrictions and protect privacy | Load balancing, protecting the server |

#### Features of Anonymous Proxies and Transparent Proxies

**Anonymous Proxies:**
- Hide the client's real IP address, protecting user privacy.
- The proxy server passes requests to the target server, and the client's IP is not disclosed.
- Commonly used for accessing restricted websites, anonymous browsing, and other privacy-related scenarios.

**Transparent Proxies:**
- Do not hide the client's real IP address, passing it directly to the target server.
- The proxy server modifies requests so that the target server can obtain client information.
- Mainly used for caching web content, reducing bandwidth usage, and accelerating network access.
