c# cefsharp browser trying to set proxy [closed]

Answer 1

You double set CefSettings. You must first configure. Configure is once in project and it should be before first call InitializeComponent() in your application.

public debug()
{
   Configure();
   InitializeComponent();
   CreateNewBrowser();
}

public void Configure()
{
   CefSettings cfsettings = new CefSettings();
   cfsettings.CefCommandLineArgs.Add("proxy-server", "200.29.191.149:3128");
   cfsettings.UserAgent = "My/Custom/User-Agent-AndStuff";
   Cef.Initialize(cfsettings);
}

public void CreateNewBrowser()
{
   browser = new ChromiumWebBrowser("https://whatismyipaddress.com/");     
   this.Controls.Add(browser);
   browser.Dock = DockStyle.Fill;     
}

I have same trouble with SefSharp3. I launch CEF3 with same configurations

--proxy-server=...

and it works fine. I think it is a bug. And CefSharp3 have so much bugs I will use C++ CEF sources.

Answer 3

If you are using a proxy type different "http", you must set it in proxy-schema e.g. as shown following

cfsettings.CefCommandLineArgs.Add("proxy-server", "socks5://200.29.191.149:3128");
