[squid-users] custom error messages

Hi,

I'm trying customized the errors messages generated by squid in
/etc/squid/errors/. Now I have added an image (logo.gif) to the ERR_* files,
however, the error messages cannot display the correct image (it adds
http://deniedsite/logo.gif). I tried the putting the static path for the
image, but it too can't be displayed. May I ask how can I fix this? Also how
do I suppress/change the caption "Generated ... (squid2.5STABLE2)." that is
generated every the error page is displayed?

Regards,
Norman
