Add a proxy to your own script, in plain English

In a browser or an app, a proxy usually goes into a settings screen and no code is involved. These guides cover the other case: a program you wrote yourself, such as a script for a class or a small project, that has to fetch web pages. Choose your language to see where your four proxy details (host, port, username and password) go, with a short sample that prints the IP address a website sees. Only point it at sites whose terms allow it, and keep within the law where you live.
