Hello Stephen,
_My question is about HTTPS. If my understanding of the IPP "Encoding
_and Transport" document (RFC2910) is correct, IPP uses HTTPS via TLS
_by sending the Upgrade header (section 8.1.2 Transport Layer
_Security). Looking at the SSL Guide, it seems like HttpClient supports
_this: "HttpClient provides full support for HTTP over Secure Sockets
_Layer (SSL) or IETF Transport Layer Security (TLS) protocols...".
AFAIK, we're not supporting upgrade of a plain HTTP
connection to HTTPS. We only support dedicated https:
connections so far. HttpClient 4.0 should be flexible
enough to add support for protocol upgrades.
hope that helps,
Roland
