The process involves matching all requests for an
RewriteCond %{REMOTE_ADDR} !^120\.120\.120\.120
RewriteRule ^admin/.* - [L,R=403]
RewriteCond %{REMOTE_ADDR} ^120\.120\.120\.120
RewriteRule ^admin$ - [L,R=403]
If you want to control this IP using a script, you can add 2 lines
###CUSTOM RULES### # your rules will appear here using php script ###CUSTOM RULES###
Now add a script, say happy.php
and use the following code:
$htaccess = file_get_contents('.htaccess');
$ip= str_replace(".","\.",$_SERVER['REMOTE_ADDR']);
$rules="RewriteCond %{REMOTE_ADDR} !^".$ip."
RewriteRule ^admin/.* - [L,R=403]
RewriteCond %{REMOTE_ADDR} !^".$ip."
RewriteRule ^admin$ - [L,R=403]";
$problem="###CUSTOM RULES###\r\n".$rules.
"\r\n###CUSTOM RULES###";
#please copy the next line carefully, no extra spaces or new lines
$solution=preg_replace('/###CUSTOM RULES###.*?###CUSTOM RULES###/sm',$problem,$htaccess);
file_put_contents('.htaccess', $solution);
you can also specify your error page for specific http code: 403ErrorDocument 403 /er.htm
