How to Use Pac Proxy? about downloader HOT 4 CLOSED

Please try the below way in a new console application and see you can do it or not?

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(Url);
request.AllowAutoRedirect = true;
WebProxy myProxy = new WebProxy("www.myserver.com/proxy/can.pac", true);
myProxy.Credentials = new NetworkCredential("user", "password");
request.Proxy = myProxy;
HttpWebResponse response = (HttpWebResponse)Request.GetResponse();

Thanks.

now i get this error

System.Net.WebException: 'The remote server returned an error: (421) Misdirected Request.'

this is my pac url
http://raw.githubusercontent.com/ghost1372/HandySub/master/Proxy/can.pac
if you set in internet options you can access youtube and other websites

but I found that any program created with .NET Core suffers from these problems and errors. There are no problems with the .NET Framework

from downloader.

This is a .NET issue and no related to the Downloader library. Because I try to use this proxy with HttpClient or HttpWebRequest in .Net Core and get some errors.
I tried the below options in Downloader or HttpClient or pure HttpWebRequest:

Proxy = new WebProxy() {
    Address = new Uri("https://raw.githubusercontent.com/ghost1372/HandySub/master/Proxy/can.pac"),
    UseDefaultCredentials = false,
    Credentials = System.Net.CredentialCache.DefaultNetworkCredentials,
    BypassProxyOnLocal = true
}

So the httpClient get an error: System.NotSupportedException: Only the 'http' scheme is allowed for proxies.
I search this error and seem this issue is from .NET Core and many browsers only support http proxies, https proxies are not yet widely supported.
Please see Unable to connect to HTTPS endpoint through WebProxy issue of .NET Core.

Note: your proxy address is not real http and redirected on https and if you set the http on the proxy address you get an error:
The remote server returned an error: (404) Not Found.
Please test your proxy address on HttpClient or HttpWebRequest and if that has no issue so the downloader must be working correctly.

Yes, unfortunately, the problem is with .NET Core, anyway, thank you.
