wiki.ipfire.org - Web Proxy Auto-Discovery Protocol (WPAD) / Proxy Auto-Config (PAC) shows lines in the config which might need to be adjusted in order to get it working.
I’ve changed
reqadd X-Forwarded-Proto:\ http
to
http-request add-header X-Forwarded-Proto http
The other one throws the warning “option httpchk : hiding headers or body at the end of the version string is deprecated. Please, consider to use ‘http-check send’ directive instead.”
option httpchk HEAD /wpad.dat HTTP/1.1\r\nHost:\ 127.0.0.1:81
Is the first change I googled correct and how could I circumvent the warning?
