HTTP代理服务器的作用 Web安全,应用集成,性能优化

1. 代理

In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers

A proxy server may reside on the user‘s local computer, or at various points between the user‘s computer and destination servers on the Internet.

  • A proxy server that passes requests and responses unmodified is usually called a gateway or sometimes a tunneling proxy.
  • A forward proxy is an Internet-facing proxy used to retrieve from a wide range of sources (in most cases anywhere on the Internet).
  • reverse proxy is usually an internal-facing proxy used as a front-end to control and protect access to a server on a private network. A reverse proxy commonly also performs tasks such as load-balancing, authentication, decryption or caching.
