How to set environment variable for HTTP_PROXY?

What does setting HTTP_PROXY do?

We set it because we need to send to a proxy, so we tell the browser where that proxy is.

The proxy is used by the web browser to talk to the back-end server. The HTTPPROXY environment variable is used when we are using curl. It's also used by the back-end server, but for sending an HTTP response.

Curl -i -o /dev/null --proto=tls. If you had set an HTTP proxy on your network computer (behind your home router), then your web browser would need to use that proxy to talk to the back-end server. When you connect from your home computer to your web browser, it tries to contact the back-end server using its configured proxy, which it uses to send its HTTPS request. When the HTTPPROXY environment variable is set, curl works in the same way as your web browser when it requests an SSL (HTTPS) page from a back-end server. However, curl can be used without requiring an HTTP proxy on the back-end server.

Setting HTTPPROXY does not configure a web proxy or an SSH proxy. You could define a proxy on your web browser and configure a custom browser setting to access back-end servers through that proxy, but that does not help for connecting to an SSL (HTTPS) server behind your home router. How do I view HTTP responses from my web browser? After installing the Java plug-in (available in the Downloads tab of the JDK), you can use the built-in web browser that comes with Java 11. How do I install Java 11 on macOS? There is no easy way to install Java 11 on macOS. If you have downloaded the macOS dmg file, double click the file to mount it as a disk image (using macOS Disk Utility or the Files app).

Click Open on the Info window. Enter the password, if required. Click Continue. Now, read the "Java version information" at the bottom of the window and check the box if you want Java 11. If you don't want Java 11, click Cancel.

Click Install. Now, double click the Java icon. Click Restart Now.
