Reminder: Upgrade header Protocols should support version

[pyfisch]

As defined in http://tools.ietf.org/html/rfc7230#section-6.7 a protocol consists of a name and an optional version token.

I don't understand what the action is for this issue. Does the Upgrade header need to be changed?

[pyfisch]

Yes we need to change Upgrade header field. (What means "need" we can also keep it but do not implement the RFC)

The RFC says:

     Upgrade          = 1#protocol
     protocol         = protocol-name ["/" protocol-version]
     protocol-name    = token
     protocol-version = token

We do:

     Upgrade          = 1#protocol
     protocol         = text
