that will make life really hard for intermediaries.  When can you write 
your cache index information, if information will be countermanded.

I would argue to deprecate tunnelling.

yes deprecate.

It's a major nightmare to lock down.  Crypto should be done with the 
knowledge of the intermediary.

the requirement for scanning content for malware at a gateway is not 
going away, it's getting bigger.

So, I would propose

a) support for SSL/TLS connections to the proxy
b) support for directing the proxy to make an upstream SSL/TLS 
connection, e.g.

GET https://www.wingate.com/secure/ HTTP/x.x
