Hello,
I am configuring a transparent squid proxy, but I also intend to use the same box in a non-transparent environment, meaning hard-coding the proxy server IP in the browser settings.
Below is my squid.conf and it's working fine in a transparent squid environment.

However, the settings above is not working for HTTPS when the squid proxy IP is hardcoded directly on a browser. I kept getting the error below.
TAG_NONE/405 3440 CONNECT error:method-not-allowed - HIER_NONE/- text/html
It can fix the problem by changing the http_port parameter below, but then, it starts giving error in transparent proxy.
