The proxies pass the data through to where? How does the proxy know where
to forward the data on to unless it can inspect the headers of the
request?

No, if you are using a general HTTP proxy for an outgoing connection, the
client software needs to be proxy aware, enough to tell the proxy which
server it wants to connect to. This is done using the CONNECT command. SSL
handshake occurs after that with the target server once that connection is
set up.
