Sometimes you want your web services to use an SSL communications channel, but for one reason or another you cannot use a SSL certificate from a major CA.
Just this past week we had just such a need at work. A coworker of mine was having difficulties making web service calls over SSL when the certificate’s CA could not be trusted by .NET. I had mentioned to him that I had done something similar in the past, and offered my help.

protected void Page_Load(object sender, EventArgs e){
ServicePointManager.ServerCertificateValidationCallback
= new RemoteCertificateValidationCallback(certExaminer);
}
