htaccess custom 403 just for one IP

how can i do this?
i`ve restricted POST fot that ip and i want JUST that person to see a special 403 message or to see a different 403 error page
something like:

IF REMOTE_ADDR == IP
ErrorDocument 403 specialmessage.html
/IF


this is how i`ve restricted POST to that ip

<Limit POST>
order allow,deny
allow from all
deny from IP
</Limit>

Code (markup):

 

With this code all sites requested from the ip 127.0.0.1 (you have to change that to the Ip you want) will be redirected to specialmessage.html.

RewriteEngine On 
RewriteCond %{REMOTE_ADDR} ^127.0.0.1$ [NC] 
RewriteRule ^(.*)$ http://www.domain.com/specialmessage.html [R]

can i do this just for the 403 file? if the server sends a 403 error to that ip to rewrite the page frm 403.shtml to http://www.domain.com/specialmessage.html ?

 

RewriteEngine On 
RewriteCond %{REQUEST_URI} ^/folder/403.shtml [R,L]
RewriteCond %{REMOTE_ADDR} ^127.0.0.1$ [NC] 
RewriteRule ^(.*)$ http://www.domain.com/specialmessage.html [R]
