Redirect HTTP and HTTPS properly in htaccess

I want to redirect

http://www2.mydomain.com/some-filename.php to http://newmydomain.com/some-filename.php And https://www2.mydomain.com/some-filename.php to https://newmydomain.com/some-filename.php

My "www2.mydomain.com" domain doesn't have the valid SSL, but still if the user access https then I need to redirect him to new domain with https only.

I have written the following code in .htaccess but it is redirecting to HTTP all the time.

<ifModule mod_rewrite.c>    

    RewriteEngine On

    RewriteCond %{HTTPS_HOST} ^www2\.mydomain\.com$ [NC]
    RewriteRule ^(.*)$ https://newmydomain.com/$1 [L,R=301]

    RewriteCond %{HTTP_HOST} ^www2\.mydomain\.com$ 
    RewriteRule ^(.*)$ http://newmydomain.com/$1 [L,R=301]

</ifModule>

Please let me know what I am doing wrong and what is the correct code to do this kind of redirects.

You aren't checking whether the incoming request is HTTPS or not. You can combine the two with a bit of clever regex grouping:

<ifModule mod_rewrite.c>
  RewriteEngine On

  RewriteCond %{HTTP_HOST} ^www2\.mydomain\.com$ [NC]
  RewriteCond %{HTTPS}:s (on:(s)|off:s)
  RewriteRule ^(.*)$ http%2://newmydomain.com/$1 [L,R=301]

</ifModule>

There isn't an %{HTTPS_HOST} variable, as it's the "Host:" request field. All the %{HTTP_(something)} variables are request fields, e.g. %{HTTP_USER_AGENT}, %{HTTP_COOKIE}, %{HTTP_REFERER}, are all request fields; User-Agent:, Cookie:, Referer:.

The second condition checks if the request is HTTPS or not, and if so (on), it captures the "s" which is backreferenced by %2, thus turning the redirect to https://, otherwise, just http://.
