Description Mathias 2014-03-28 09:42:09 UTC
When I create a connection to a https Server using the HttpWebRequest class and the TLS (1.0) protocol is used, the "Renegotiation indication" extension (defined in RFC5746, http://tools.ietf.org/html/rfc5746) is not set in the request. This extension is required by TLS, since it mitigates a big security problem in the TLS protocol. Some servers require that extension (for instance apache with mod_nss an NSSRequireSafeNegotiation set to on) causing HttpWebRequest to throw a WebException.
