Nginx正向代理配置

通过把Nginx设置为正向代理，我们就可以在局域网中用运行着Nginx的主机作为正向代理服务器了。那什么是正向代理和反向代理呢？正向代理和反向代理-百度百科

正向代理：如果把局域网外的Internet想象成一个巨大的资源库，则局域网中的客户端要访问Internet，则需要通过代理服务器来访问，这种代理服务就称为正向代理。

反向代理：如果局域网向Internet提供资源服务，让Internet上的其他客户端来访问局域网内的资源，使它们必须通过一个代理服务器来进行访问，这种服务就称为反向代理。正向代理和反向代理逻辑正好相反。

Nginx正向代理涉及到的指令较少，下面直接贴上其配置文件内容。
