Answer 1

Add RewriteEngine On before RewriteCond to enable your rewrite rules:

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

And if you have https:

RewriteEngine On

RewriteRule .? - [E=PROTO:http]

RewriteCond %{HTTPS} =on
RewriteRule .? - [E=PROTO:https]

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