Code: Visual Basic.NET
Dim threadRunner As ThreadRunner
Dim Wv As WebView
Dim list As New List(Of String)
For i = 1 To 5
threadRunner = New ThreadRunner()
Wv = threadRunner.CreateWebView()
threadRunner.Send(Sub()
Wv.LoadUrlAndWait("https://www.baidu.com/")
End Sub)
Dim L As New List(Of String)
Dim CookieCollection As EO.WebEngine.CookieCollection
CookieCollection = Wv.Engine.CookieManager.GetCookies("https://www.baidu.com/", True)
For j As Integer = 0 To CookieCollection.Count - 1
L.Add(CookieCollection(j).Name & "=" & CookieCollection(j).Value)
Next
Dim s As String = Join(L.ToArray, "; ")
list.Add(s)
Wv.Engine.CookieManager.DeleteCookies(Nothing, Nothing)
Wv.Close(True)
Wv.Destroy()
Wv.Dispose()
threadRunner.Dispose()
Next
MessageBox.Show(String.Join(vbCrLf & vbCrLf, list))
5 times get the cookie as follows:

You can see that every the "BIDUPSID" key's value is the same, why ??? :-] I think every time I get it, it's totally different. How I need to do ?

Hi,
You can try these steps and see if it works for you:
1. Explicitly create an Engine object;
2. Set the Engine's CachePath;
3. Create a ThreadRunner with that Engine and use it to load the page;
4. Destroy the WebView and ThreadRunner;
5. Stop the Engine;
6. Delete the entire Engine.CachePath directory;
The issue you are running into could be because CookieManager.DeleteCookies works asynchronously in the background, so it does not guarantee the cookies are deleted when it returns.
Thanks!

Thanks! Thank you very much. I succeeded in the test.
