Complete tutorial onApache Documentation
Below is the code I put on .htaccess file on the folder/site which I want to protect

Order allow,deny
Deny from all
Allow from profusehost.net
ErrorDocument 403 /error/HTTP_NOT_FOUND.html.var

Order allow,deny
 tell apache to evaluate allow list then deny list, if any client doesn''t match in allow and deny list it''ll denied

Deny from all
denied all client

Allow from profusehost.net
but access from *.profusehost.net is allowed, and its sub-domain and host under domain profusehost.net

ErrorDocument 403 /error/HTTP_NOT_FOUND.html.var
This is for displaying error 404 Object Not Found instead of error 403, so client will assume the folder is not exist.

                                  

since I know domain .web.id were given for free right now. I am asking several friends.

"Hey do you want a domain with your name .web.id?"

some of said Yes. and for reducing fee for webhosting I choose free webhosting.

Kusma with domain kumay.web.id is hosted at pandela using nucleus

Ridwan with domain ridwanfi.web.id using BoastMachine

Suherman with domain suherman.web.id using sBlog
