' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim http As New Chilkat.Http

' Call SetSslCertRequirement to require that the SSL server certificate's domain
' matches only the domain we are intending to communicate with.

' In this example we will test with the URL https://wrong.host.badssl.com/
' which intentionally has an SSL certificate that does not match "wrong.host.badssl.com"

http.SetSslCertRequirement("SAN","wrong.host.badssl.com")

' Also validate the server cert..
http.RequireSslCertVerify = True

' Try sending the request.  It should fail within the SSL/TLS handshake
' because the server's certificate does not match the domain "wrong.host.badssl.com"
Dim html As String = Await http.QuickGetStrAsync("https://wrong.host.badssl.com/")
If (http.LastMethodSuccess = False) Then
    Debug.WriteLine(http.LastErrorText)
Else
    Debug.WriteLine("Unexpected success.")
End If
