# disclaimer: i wrote this script for me, and it works for me.
# if it doesnt work for you, or makes your server explode,
# thats life. please email with questions or bug reports.
# set these variables to configure the script:
# set $domain to your domain name (no www)
$domain = your.domain.com;
# set $docroot to the url of the directory which contains your
# .htaccess file. dont include trailing slash.
$docroot = http://your.domain.com;
# font face youd like to use on the 404 page
$fontface = verdana;

# background color of the 404 page (default is white)
$bgcolor = #ffffff;
# text color youd like to use on the 404 page (default is black)
$textcolor = #000000;
# this script is capable of mailing the details of each 404 error
# to the webmaster. use the $reportlevel variable to control when
# you receive these reports.
#
# 0 = dont use the email capabilities at all
# 1 = send email only if the errors referer contains your domain name
# (i.e. the 404 was generated by a broken link on your site)
# 2 = send email any time a 404 error is generated (useful for tracking
# broken links at other sites which link to you)
$reportlevel = 2;
# set $emailaddress to the email address of whoever should be
# notified of 404 errors. dont escape the @ symbol. this will also
# be used as the from address on any emails the script generates.
# you can leave this unassigned if youre not using email features.
