This link will be of interest to you  http   msdn microsoft com en-us library ds8bxk2a aspx     For http connections  the WebRequest and WebResponse classes use SSL to communicate with web hosts that support SSL  The decision to use SSL is made by the WebRequest class  based on the URI it is given  If the URI begins with  https    SSL is used  if the URI begins with  http    an unencrypted connection is used

You re doing it the correct way but users may be providing urls to sites that have invalid SSL certs installed  You can ignore those cert problems if you put this line in before you make the actual web request   ServicePointManager ServerCertificateValidationCallback   new System Net Security RemoteCertificateValidationCallback AcceptAllCertifications     where AcceptAllCertifications is defined as  public bool AcceptAllCertifications object sender  System Security Cryptography X509Certificates X509Certificate certification  System Security Cryptography X509Certificates X509Chain chain  System Net Security SslPolicyErrors sslPolicyErrors        return true
