HttpGet support Alt-Svc

[zhangnew]

The Alt-Svc HTTP header allows a server to indicate that another network location (the "alternative service") can be treated as authoritative for that origin when making future requests.

这东西有人在用吗

[zhangnew]

我也是最最近才发现的，这样访问家宽的服务就不需要加端口了，域名指向公网用 443 端口的服务，AltSvc 域名指向家宽的任意端口，只需要消耗一点点公网流量就能访问家宽服务。

这不得客户端能直接访问你的家宽，也就是解决一个域名问题吧

对的，agent 先访问公网 443 域名得到 AltSvc 的家宽域名和端口，再去测试一下家宽，都没问题返回成功

直接访问家宽就好了，加这个增加复杂度

这个家宽的服务是通过 lan-expose 暴露在同一个端口，直接请求的话需要几个 header 才可以，agent 也不支持加 header， 没想到其他好的办法了

header 示例：

curl -H "Connection: Upgrade" -H "Upgrade: x.example.com" -H "Host: x.example.com" https://home.example.com:690

如果你确实需要，优化下代码
