Because the protocol is unknown to Squid for SSL requests.

PROTO_HTTPS is reserved for when Squid has really received a https://
URL, and used for this purpose in the current Squid sources.

Squid recieves https:// URLs in two cases

  a) When it is used as a SSL enabled accelerator (https_port
directive).

  b) When Squid is used as a SSL gateway for HTTP clients not natively
supporting SSL, such as old versions of LYNX etc..

And actually also a third case which should not happen...

  c) When brosers bug out and reuses a plain unencrypted http proxy
connection for https:// requests.. many versions of Netscape 4.X is
known to do this..
