This won't work.  For example

     1.0 UA ---------> 1.1 Proxy ---------> 1.0 Origin Server

will result in a 1.1 cookie being sent to a 1.0 user agent.

The only features of HTTP that can depend on a minor version number
change are those that are interpreted by neighbors in the communication.
Other feature changes require changes to the content, such as a 
different header field name.
