What happens if you use Squid as an HTTPS proxy rather than an HTTP
proxy? In other words, can you configure your client to connect over SSL
to Squid's https_port instead of connecting over plain TCP to Squid's
http_port? After that connection is established, the client will send
CONNECT in both cases, but perhaps the "network" will not reset the SSL
connection to Squid because it would not be able to see HTTP[S]
transaction boundaries inside that SSL connection?

If SSL connections to Squid are prohibited on your network, and only one
HTTP transaction is allowed per HTTP connection, then I cannot think of
a way to send standard HTTPS requests through a standard HTTP proxy.
