Hello all,
I am sorry maybe you have seen lots of like these questions but i have
already searched archive and could not fix my problem. I am using
squid-2.6.STABLE18p0 with OpenBSD 4.3. I can not use https as
transparent proxy like http. I redirected http and https traffic to
squid. http works properly. This the error log from access.log -->
TCP_DENIED/400 1558 NONE error:unsupported-request-method - NONE/-

What you are attempting is called a man-in-the-middle attack.
Transparent interception of HTTPS traffic is (by design) not possible.
Squid 3HEAD includes a feature called sslbump
(http://wiki.squid-cache.org/Features/SslBump) that will facilitate the
interception and decryption of HTTPS traffic.
How can i fix it ?
Use WPAD, statically assign a proxy server, or let SSL traffic bypass Squid.
Thanks
