https域不通过htaccess重定向到子域

Question

我的htaccess文件从域名重定向到子域，然后确保它是HTTPS。当HTTPS与域名一起使用时，所有工作都可以预期：

https://example.co.uk              FAILS
https://www.example.co.uk          OK - https://www.example.co.uk  
http://example.co.uk               OK - redirects to https://www.example.co.uk
http://www.example.co.uk           OK - redirects to https://www.example.co.uk

htaccess文件看起来像这样

#First rewrite any request to the wrong domain to use the correct one
RewriteCond %{HTTP_HOST} ^example\.co\.uk$
RewriteRule ^(.*)$ https\:\/\/www\.example\.co\.uk/$1 [R=301,L]

#Now, rewrite to HTTPS:
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
