Use Htaccess-File To Redirect All Requests Possible: Http To Https etc

[tarifa]

hi there - good day dear experts 

This is the .htaccess code for permalinks in WordPress.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

we have the following ingrediences: 

-f and -d part means to give real directories and files higher priority.

how it works: 

^index\.php$ - [L] prevents requests for index.php from being rewritten, 

to avoid an unnecessary file system check. If the request is for index.php the directive does nothing

 - and stops processing rules [L].

This following block is all one single rule: this rule says that if it is not a real file and not a real directory, reroute the request to index.php.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

well - the index.php itself interprets the URL that was requested by the client-machine (since PHP can see the requested URL using $_SERVER['REQUEST_URI']) and it calls the correct code for rendering the page the user requested.

and now to the issue of today:  i want to do this for using to redirect HTTP to HTTPs with mydomain - what kind of htaccess do i need to run?

what is wanted:  i want to do this for using to redirect HTTP to HTTPs with https://www.mydomain.com and https://mydomain.com/ and http://mydomain.com - what kind of htaccess do i need to run 

With my current .htaccess, this is what happens:

 

https://www.mydomain.com/ - i need this 

https://mydomain.com/ -i need this that subsequently  redirects to the above which would be  great

, it should redirect to the https version: 

note: i all way thought that i need to have a new /(and extra vhost to do this)

http://www.mydomain.com/

http://mydomain.com/

Here is the .htaccess:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
	# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
	

again: what is wanted: i want to have a redirect that helps in each time & situation With my current .htaccess, 

 

https://www.mydomain.com/ - i need this 
https://mydomain.com/ -i need this that subsequently  redirects to the above which would be  great

what is aimed: all options should load fine, it should redirect to the https version:  
note: i allways thought that i need to have a new /(and extra vhost to do this). but perhaps i do not need a second vhost!? Perhaps i can do it with .htaccess too!?

http://www.mydomain.com/
http://mydomain.com/

can you help out here..!?
