I built and installed squid 3.5.23 as follows:
- ./configure --prefix=/usr/local/squid
- make all
- make install
Here is the default squid.conf used by the version. I made minimal modifications to to the file to make my setup anonymous:
forwarded_for delete
request_header_access Via deny all
request_header_access Cache-Control deny all
After I got the (remote) proxy server running, I confirmed that I could configure my (local) browser to send traffic through it. I then took it to the next step, and had my router send all traffic originating from my local network to my proxy server:
iptables -t nat -A PREROUTING -s 192.168.11.0/24 -d ! 192.168.11.0/24 -p tcp -j DNAT --to-destination 100.200.30.40:3128
However, all of my requests came back with a 400 from squid (BAD REQUEST). On investigating further, I discovered that the request headers were using relative urls (my browser is smart enough to always use absolute urls if it knows it is talking to a proxy server).
I know HTTP 1.1 headers are required to have a Host header, which squid can use to determine the original destination of packets it receives. How do I configure the proxy server to use that header? I am looking for the squid 3.5 equivalent of httpd_accel_uses_host_header on
