It's hard for me to see how this could fit SSL and HTTP protocols, sorry.
Someone else might be lucky here

"consume certificate" probably means "engage in a protocol to prove 
the name certified". It's still open question what protocol both do the job
and is implemented by popular browsers.

Hope you could hit your target with other tools like passord-based
proxy access or maybe proxy access controlled by IPSec

There was a document by Ari Luotonen; just found it at (single line!)
http://www.web-cache.com/Writings/Internet-Drafts/draft-luotonen-web-proxy-tunneling-01.txt
It describes the method how a proxy could handle HTTPS requests

Please note HTTP details might be off-topic for this list
