Problems redirecting to the www subdomain about hstspreload.org HOT 4 CLOSED

Redirect to HTTPS first:

RewriteCond %{HTTPS} off
RewriteRule ^/?(.*) https://%{HTTP_HOST}/$1 [R,L]

If you want the main site on the www subdomain, redirect to www once you're on HTTPS:

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

EDIT: Fix regex, as described below

Thanks for the pointers. I have tried setting my .htaccess like that, but it doesn't seem to work. If I set it as follows:

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" env=HTTPS

RewriteCond %{HTTPS} off
RewriteRule ^/?(.*) https://%{HTTP_HOST}/$1 [R,L]

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

Then the page itself refuses to load due to 'too many redirects', and the HSTS preload page gives me this error twice: 'There are more than 3 redirects starting from http://acmewidgets.com.'

Am I coding this in wrong?

Whoops, I think the second-to-last line needs to be:

`RewriteCond %{HTTP_HOST} ^acmewidgets.com$ [NC]`

Closing this, since it's not a bug to do with the submission site.
