How do I redirect incoming requests from domain.com to www.domain.com via HTTP and HTTPS using .htaccess?

Question

I have the script:

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

Rewrite rule to redirect /old to /new

RewriteCond %{REQUEST_URI} ^/old$
RewriteRule   . /new [L,R=301]

Which will redirect http://example.com to http://www.example.com, but would like this script to work the same if a user requests the URL via HTTPS? I can't seem to find a solution anywhere.... =/

Anyone have any ideas?

Thanks

Answer 1

Use this rule:

RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.example.com%{REQUEST_URI} [L,R=301]

Answer 2

RewriteCond %{HTTPS} =on
RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteRule ^(.*)$ https://www.domain.com/$1 [L,R=301]

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

It appears that this can't be done in our case.... apparently because the certificate must first be accepted by the browser. In the event that it is not accepted, the redirect will not be allowed to occur because of the browser's "warning" message.
