The work I was doing on Squid having an internal web server got mired in
the QA feature creep and abandoned.

Currently I use this config:

 acl WPAD urlpath_regex ^/wpad.dat$
 deny_info 200:wpad.dat WPAD
 http_access deny WPAD
 reply_header_access Content-Type deny WPAD
 reply_header_replace Content-Type application/x-ns-proxy-autoconfig


With a symlink from /usr/share/squid/errors/templates/wpad.dat pointing
to my /etc/squid/wpad.dat file.

This has the added benefit that the wpad.dat can use Squid custom error
page %h macro to insert the proxy hostname dynamically without needing a
different wpad.dat for each POP.

I do have to take care that the templates package being upgraded does
not erase the symlink though.
