htaccess: trying to serve different pages

[sesme]

Hi,
I'm new to htaccess and my isp is not helping.
What I'm trying to do is serve a page called "block.htm" to the ip's and domains that I have listed as "deny."

I'm not sure if they see it or not. i do know the way it is now the "block" page gets pushed to any 403/404 error. so anybody that types a wrong address gets it.

So, i want ONLY those being denied to get the block.htm file and everyone else to get normal 403/404.

THANKS for all help

here is what i have now:
<Limit GET>
order allow,deny
allow from all
deny from .xxx.net
</Limit>

ErrorDocument 403 http://www.xxxxx.com/block.htm

ErrorDocument 404 http://www.xxxxx.com/block.htm

deny from 192.167.44.33

[firepages]

403 and 404 documents do different things ,

404's are served when a page can not be found
403's are served when permission is denied denied

so try serving different pages for different situations ... eg

ErrorDocument 403 /path/block.htm
ErrorDocument 404 /path/custom_404.htm
