在Go 的实现里面,每个 interface 接口变量都有一个对应 pair,这个 pair 中记录了接口的实际变量的类型和值(value, type),其中,value 是实际变量值,type 是实际变量的类型。任何一个 interface{} 类型的变量都包含了2个指针,一个指针指向值的类型,对应 pair 中的 type,这个 type 类型包括静态的类型 (static ty...

Intelligent HTTP, SOCKS5 proxy: the program will automatically determine whether the site which it access is blocked, if the site is blocked, the program will use parent proxy (the premise is you set up a parent proxy) to access the site. If the site isn't blocked, in order to speed ...
By default, the proxy will intelligently determine whether a website domain name is inaccessible. If it is not accessible, it will go to the upper level HTTP proxy. With --always, all HTTP proxy traffic can be forced to go to the upper HTTP proxy. proxy http --always -t tls -p ":...
