proxy_pass via HTTP proxy

[cavedon]

Hi,

I am trying to configure my nginx instance so that it "proxy_pass"es to
another HTTPS server S.
However, in order to reach S, I need to go though an HTTP server P. This
means nginx would need to connect to P, issue a CONNECT request, and then
tunnel the HTTPS request to S.
Is this supported? How to enable it?
I could not find mention in the documentation, and it is kind of hard to
search for :)

Thank you,
Ludovico
