Use Proxy for Git/GitHub

Generally, the Git proxy configuration depends on the Git Server Protocol you use. And there're two common protocols: SSH and HTTP/HTTPS. Both require a proxy setup already. In the following, I assume a SOCKS5 proxy set up on localhost:1080. But it can also be a HTTP proxy. I'll talk about how to set up a SOCKS5 proxy later.

SSH Protocol

When you do git clone ssh://[user@]server/project.git or git clone [user@]server:project.git, you're using the SSH protocol. You need to configurate your SSH client to use a proxy. Add the following to your SSH config file, say ~/.ssh/config:

ProxyCommand nc -x localhost:1080 %h %p

Enable #enable-devtools-experiments flag in chrome://flags section.
Open Chorme Devtools and check Settings > Experiments > Allow extensions to load custom stylesheets.

Create the following four files in a dedicated folder.

3.1. devtools.html

<html>
<head></head>
<body><script src="devtools.js"></script></body>

Embedded Variables

The ngx_http_core_module module supports embedded variables with names matching the Apache Server variables. First of all, these are variables representing client request header fields, such as $http_user_agent, $http_cookie, and so on. Also there are other variables:

$arg_name
argument name in the request line
