Proxy under Windows.

[nanoric]

Sorry for asking this question again and again.
I have tried the following(enable_global_proxy.bat):

netsh winhttp set proxy proxy-server="socks=192.168.0.201:2000"
setx all_proxy socks5h://192.168.0.201:2000/
setx https_proxy http://192.168.0.201:2001/
setx http_proxy http://192.168.0.201:2001/

This USED to work about a month ago. But for now it does'nt work.

vcpkg strucks at the first invoke of install, when downloading

setx https_proxy http://192.168.0.201:2001/
setx http_proxy http://192.168.0.201:2001/

setx https_proxy http**S**://192.168.0.201:2001/ ?

for the http schema:
I don't have a https proxy(which needs certificates).
I don't know if it is necessary to use a https proxy to access a https site. But I can use a http proxy to access https site in chrome.(And, you know, the proxy i'm using in chrome is just the one I set in this script.). So maybe it is not a problem.

I don't know much about how docker manager its network access.
I only know the proxy setting of docker daemon effects how docker pulls images,
Does it still effect how its container accessing network (by using WinHTTP)?

[nanoric]

Maybe the script enabling proxy never works.
The reason I build image succeed a month ago is maybe just because I can access github without proxy at that time.

And finally I turn to another solution
To avoid vcpkg to download these and fails, download/install them manually is a better solution.

All the tools are listed in scripts/vcpkgTools.xml
And by just set environment variable VCPKG_FORCE_SYSTEM_BINARIES, Pre-download/install all the tools that vcpkg needs is possible. #4501 (comment)
