Yep - that's what you need when you want to make sure
that your programmatic SSL WebRequest accepts the SSL
challenge. At least when you are encountering the
Exception: "The underlying connection was closed.
Could not establish trust relationship with remote
server."
Before you call call the web
request, you then set the static property
CertificatePolicy on the ServicePointManager class
like so:
ServicePointManager.CertificatePolicy =
new
AcceptAllCertificatePolicy();
And that should work like a treat!
