rewrite non-www to www

Hi,



Can anyone help me with this?

I'm trying to rewrite non-www to www



I already have this in the nginx.conf Customization (custom 3) box to rewrite http to https



|*if SSL_TEMPLATE="0"|

rewrite ^(.*)$ http://ift.tt/1sPJHUD permanent;

|*endif|



But now I also want to rewrite https://example.com to https://www.example.com



I tried some different configurations, but no success so far. :confused:
