Minimising redirect chain in .htaccess setup - wordpress

Question

I'm at a basic level of understanding when it comes to .htaccess redirects but I'm managing to just about get by with a site I'm redeveloping. I have searched Stack Overflow quite extensively, but can't understand how to put together all the advice in the context of my own situation.
I'm switching my WordPress the site to https and so far have managed to cobble together the following set-up:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{ENV:HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [NC,R=301,L]
# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I have a few bugs I'd like to iron out though, currently http:// redirects to https:// which then redirects to https://www.
How do I set up an additional rule to move everything from http:// directly to https://www. ?
Also there are some pages I'd like to redirect to new URLs in the https site. http://www.example.com/bunny to https://www.example.com/rabbit. How is the best way (least 301 chains) to redirect these from insecure to a new secure URL?

Answer 1

I advice you to replace your redirect rules to this (adapt your domain):
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.domain.com/$1 [R,L]

Answer 2

You don't need to use RewriteCond %{ENV:HTTPS} !=on
You need to something like this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.domain.com/$1 [R,L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
and in wp-admin:
wordpress site Address Url : https://Your_site_url
Site Address Url:https://Your_Site_Url
