# Traps 404 errors and mails a notice to the webmaster.
# Requires PHP 3.0 or newer, and mail capability on your system.

# If it doesn\\'t work for you, or makes your server explode,

# 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. Don\\'t include trailing slash.
$docroot = "http://your.domain.com";
# Font face you\\'d like to use on the 404 page
$fontface = "Verdana";
# Font size you\\'d like to use on the 404 page
$fontsize = "2";
# Background color of the 404 page (default is white)
$bgcolor = "#ffffff";
# Text color you\\'d 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 = don\\'t use the email capabilities at all
# 1 = send email only if the error\\'s 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. Don\\'t escape the @ symbol. This will also
# be used as the "from" address on any emails the script generates.
# You can leave this unassigned if you\\'re not using email features.

# a lot of echo statements if you want to retain PHP3 compat.
