HTTP - Forward Proxy


A forward proxy is a proxy application that is configured to intercept and forward every internal Http request to an destination website, hence the name Forward Proxy.

It's also known as man-in-the-middle proxy.

The proxy configuration that do the inverse (ie receives external request and routes them to internal service such as a website) is called a reverse proxy or gateway

The forward proxy sits on a local network between the local client (user) and the external destination website.

Technically, in order to get content from the origin server, the client sends a request to the forward proxy naming the origin server as the target. The proxy then requests the content from the origin server and returns it to the client.


A typical usage of a forward proxy is to intercept HTTP traffic and:



The proxy can be implemented:

Client Configuration for a server proxy


The client must be specially configured to use the forward proxy to access other sites. Ie the proxy parameters.

Example with Windows:

Windows Internet Properties Proxy


The configuration of a forward proxy on a Linux server happens with the environment variable http_proxy or https_proxy that set the proxy server location.


export http_proxy=
export https_proxy=
