+# The configuration below implements multi-language error documents through
+# content-negotiation.
+
+# 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
+
+# Required modules: mod_alias, mod_include, mod_negotiation
+# We use Alias to redirect any /error/HTTP_<error>.html.var response to
+# our collection of by-error message multi-language collections. We use
+# includes to substitute the appropriate text.
+# You can modify the messages' appearance without changing any of the
+# default HTTP_<error>.html.var files by adding the line:
+#   Alias /error/include/ "/your/include/path/"
+# which allows you to create your own set of files by starting with the
+# /var/www/localhost/error/include/ files and copying them to /your/include/path/, 
+# even on a per-VirtualHost basis. The default include files will display
+# your Apache version number and your ServerAdmin email address regardless
+# of the setting of ServerSignature.
