Suppose you have a site yourdomain.com and in the document root directory of yourdomain.com you have a directory “admin” in which you want to restrict the access to others. But you want to give access to clients from some ips.
You can do this by creating a .htaccess file under “admin” directory.
.htaccess file can be like this.
Deny from all
Allow from IP_address1
Allow from IP_address2
Allow from IP_address3
Allow from IP_address4
Allow from IP_address5
