无法设置Cookie：Cef.SetCookie（）始终返回false

Question

This issue has been puzzling me for a couple of days now. I'm completely unable to set a cookie using CefSharp .

Here's the code block that I'm expecting to work (more so because it's as naive as can be, excluding the explicit thread context switch):

Application.Current.Dispatcher.Invoke(new Action(() =>
{
    var settings = new CefSettings();
    settings.CachePath = "cookies";

    Cef.Initialize(settings);

    Cef.DeleteCookies("", ""); 
    Cef.VisitAllCookies(new CookieVisitor());  // <-- doesn't get called, so assuming we've cleared all the persistent cookies here...

    Cef.SetCookiePath("/", false);
    Cef.VisitAllCookies(new CookieVisitor());  // <-- ok guess im paranoid...
    var isSet = Cef.SetCookie("/", "username", 
                    "testuser", "tovalrsv01", "/", 
                    false, false, false, new DateTime(2020, 1, 1));

    Cef.VisitAllCookies(new CookieVisitor()); // <-- isSet is false, and i don't see the cookie that i created in the visited list...
}));

I'm just wondering if I'm missing some important concept here. I'm new to CefSharp and despite having pored over the examples and the forums, it's highly possible that I've missed something here. Would greatly appreciate any insights or pointers!

Argggh! I figured it out after more trial and errors. A post on this site helped me on my investigation:

https://groups.google.com/forum/#!topic/cefsharp/SflbtatvTqQ

Try passing in an empty string for domain rather than "/" or pass in Url as "/mywebsite" and domain as "192.16.1.6"

This made me wonder if my cookie params were being rejected for one reason or another. I ended up trying to set the cookie with these params:

var isSet = Cef.SetCookie( " http://tovalrsv01:8142/ " , "username", "testuser", "", "/", false, false, false, new DateTime(2020, 1, 1));

Specifying the URL a bit more rigorously was what did the trick. I guess DNS aliases are not good enough, sometimes. Anyways, I'm going to leave this post in case other CefSharp ers run into a similar situation.

Here is the code I have used below code to add cookie.

var mngr = Cef.GetGlobalCookieManager();
Cookie Ac = new Cookie();
Ac.Name = "<Cookie Name>";
Ac.Value = "<Value>";
mngr.SetCookieAsync(<URL to Navigate>, Ac);

Thank you for suggestion of Akash Patel. But that example doesnt work in my case(CefSharp.OffScreen 71.0.2), so I have edited it like this:

//_browser is object of ChromiumWebBrowser
var cookieManager=_browser.RequestContext.GetDefaultCookieManager(null);
Cookie cookie = new Cookie
{
    Name = name,
    Value = value
};
cookieManager.SetCookie(url, cookie);
//or cookieManager.SetCookieAsync(url, cookie);
