Okay Ive searched and could not find the .HTML page I need to configure or even the directory where I can put my custom page in her is places Ive configured but no luck still getting the same 404 page
/usr/share/apache2/error
/usr/share/squid/errors/English (this changes all pages on the internal going through the squid)
/etc/apache2
/usr/lib/apache2
