Go to any bogus URL (i.e. foo/) with the default config and you get:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /foo was not found on this server.</p>
<p>Additionally, a 506 Variant Also Negotiates
error was encountered while trying to use an ErrorDocument to handle the
request.</p>
<hr />
What's this 506 error doing here? I'm sorry but I didn't really follow
all of the variant ErrorDocument threads. =-) -- justin
