Proxy ¶

There are multiple types of proxy, and their features are different.

Open proxy ¶

An open proxy, also called dedicated or forward proxy, is a proxy that is filtering outgoing traffic.

For instance, between users of a company, and the internet, a company may set up an open proxy to prevent users from accessing some websites.

➡️ They can be anonymous (hide requester) or not (transparent).

🚀 Transparent proxies can cache frequently accessed resources.

Reverse Proxy ¶

A reverse proxy is the opposite of an open proxy. Instead of filtering outgoing traffic, it filters incoming traffic.

➡️ A reverse proxy can act as a Load balancer.

➡️ A reverse proxy can act as a WAF.

Protocols ¶

➡️ See the SOCKS proxy protocol.
