How to set HTTP_PROXY and HTTPS_PROXY environment variables?
I'm looking for a way to set the HTTPPROXY and/or HTTPSPROXY environmental variables on a server, and also have them persist across reboot.
I have searched and tested with no luck (maybe I'm asking the wrong question?). What I would like to do is be able to just type something like or in my terminal and get a webserver on a domain name resolve. What I've tried: Setting up my ~/. If this is even possible, what are my other options? To keep your user-defined environment settings in one place you can add a .environment file with environment values in /home/myuser/.environment like:
HTTPPROXY=. HTTPSPROXY=. For permanent changes add the following to /etc/environment. Export HTTPPROXY=. Export HTTPSPROXY=. For setting it in bashrc run. Source ~/.
What is HTTPS_PROXY used for?
I see HTTPPROXY and HTTPSPROXY used as environment variables all the time.
How is HTTPSPROXY different from HTTPPROXY? From wikipedia. HTTPSPROXY (and by extension HTTPPROXY) is a Unix environment variable that enables the transparent redirection of some network traffic via an HTTP proxy to a given destination on the other side of the proxy. For example, if a computer running a web browser is behind an HTTP proxy, traffic from that computer to websites will pass through the proxy server.
The following HTTP header changes take place in the request: Method: The original method used to access the resource (ie GET or POST) is now changed to GET when it makes its way to the proxy server. This does not affect HEAD and DELETE, since they are not methods of the hypertext transfer protocol.
Host: The original host name is now replaced by the proxy server's domain name. The following HTTP header changes occur in the response: Return code: A standard HTTP code of 200 is sent back. For example: HTTPSPROXY=192.168.1; HTTPPROXY=192.1
In this case the web browser requests the specified URL. But since this is a network setting, the "destination" URL you typed into your web browser could be whatever address you type in.
Here's another set of example that make more sense. HTTPSPROXY=192.1:80; HTTPPROXY=192.1:80
In this case, the web browser sends a request for We don't know the actual URL because we are using an HTTP proxy. The proxy sets the request headers so that it looks like the browser requested But, again, that URL could be anything typed into the browser.
However, you can see how HTTPPROXY would let you specify a non-http resource that just so happens to be on the same machine as the proxy server. HTTPSPROXY wouldn't let you do that, but it could just be that you can't have a http proxypushtunnel.
