exclude the spiders using mod_rewrite or <Limit GET> in .htaccess if you
can work out their IP addresses
<Limit GET>
order allow,deny
allow from all
deny from 12.18.254.62 #www.case.com
deny from mx.domactive.com # towson mail server 07 02 03
</Limit>
etc (not sure if stated domains work but IPs (and part IPs ending in "."
do) and set
ErrorDocument 403 http://someurl.com
to route the spiders to no where or somewhere if the preset 401 error page
is unsuitable
