I have the following in my htaccess to force the www in URLs:

RewriteCond %{HTTP_HOST} !^www\\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

I added all these:

RewriteCond %{HTTP_HOST} !=localhost
RewriteCond %{HTTP_HOST} !=127.0.0.1
RewriteCond %{REMOTE_ADDR} !=127.0.0.1
RewriteCond %{REMOTE_ADDR} !=::1
