Subject RE: reference to external error-page
Date Fri, 03 Jan 2003 17:12:23 GMT
If you just want custom error pages for Apache, check out the following snippet
from httpd.conf:

# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
