UnityWebRequest proxy environment variables overridden by system proxy settings

I am having an issue running Unity behind a proxy with a particular setup in Windows.

Normally I would provide the environment variables of http_proxy and https_proxy with the proxy details

Code (csharp):

1. http/s://username:password@hostname:port

That would usually suffice with the Proxy-Authorisation header is sent across with the HTTP requests



However in this instance the user also has a system level proxy configured with basic username and password authentication. This appears to result in the environment variable proxy configuration being ignored. That in itself would be OK as it is the same proxy server but when using the system proxy config Unity does not provide the Proxy-Authorisation header in the http requests. This results in 407 Proxy Authentication Required response and no traffic getting through.

Is there a way to manually provide the authentication details in the case that it uses the system proxy config or force unity to use the config from the environment variables?

Platform: Windows build
Unity version: 2017.1.2

I have tried manually setting the Proxy-Authorisation header with the following line

Code (csharp):

1. request.SetRequestHeader("Proxy-Authorization", "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes("Basic test:1234")));

This would be a horrible work around and probably to be expected results in the exception:



Has anyone found a solution to this that I am missing?

 

Cheers Aurimas-Cernius,

This is exactly what I was after.

 

@Aurimas-Cernius when was this added pls ?
I'm trying to set a proxy automatically per process for users for different Unity versions -
( I believe HTTP_proxy/HTTPS_proxy variables can be used too ? Do these all follow WWW/UnityWebRequest introduction ?)

Thank you!

 

this is what I needed thanks, took a while to find, this should probably be better documented along with the other proxy settings unity pulls in
