Proxy servers are widely used in e-commerce, and they can effectively protect corporate commercial confidential information.

E-commerce companies generate and collect a large amount of sensitive information during their operations, such as customer information, order data, inventory information, etc. Once this information is leaked, it will cause great losses to the enterprise. However, due to the public nature of network access, corporate websites directly facing the Internet also bring certain security risks. This requires a technical means to isolate the internal system of the enterprise from the external network. This is where the proxy server comes into play.

The proxy server works in the middle of the internal and external networks of the enterprise. External users access the corporate website through the proxy server, and the proxy server forwards the request internally. The benefits of doing this are:

1. Hide the true structure of the internal network: External users cannot know the IP and deployment status of specific internal servers, which makes it more difficult to attack internal systems.

2. Filter non-compliant requests: The proxy server can filter certain requests that do not meet corporate standards, and like a firewall, only allows access through IPs in the whitelist. This effectively prevents attacks.

3. Cache static content: The proxy server caches static content such as images, CSS and JS files, which reduces the pressure on the internal server and improves website access speed.

4. Request logging: As the middle layer, the proxy server can record the IP and time of all external requests, which is beneficial to future network security analysis and auditing.

5. Web content filtering: The proxy server can identify and filter malicious code that may exist in web pages, such as XSS and SQL injection, which also has a good protective effect against web attacks.

6. Load balancing: The proxy server itself can also provide load balancing functions, allocating traffic to different internal WEB servers according to certain rules to improve overall performance.

In short, by setting up a layer of proxy servers in the internal and external networks, the internal and external networks can be effectively isolated and internal information hidden, while also providing rich web application request processing capabilities. This undoubtedly provides a good means of network security protection for e-commerce companies, and can also be regarded as a "protective umbrella" for e-commerce. Practice has proven that proxy servers bring good benefits to enterprises in terms of security and performance.
