.htaccess rewrite rule for forcefully redirect https to http

Question

I have a primary domain https://www.domain.com or https://domain.com and a wildcard DNS like https://domain.com/index.php?name=abcd redire

Answer 1

You already have the rule for rewriting to https, the only thing left is excluding login.php

RewriteCond %{HTTP_HOST} ^(?:www.)?(?:domain\.com)$
RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} !^/login\.php$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=302,L]

If login.php is requested with https, rewrite it to http

RewriteCond %{HTTP_HOST} ^(?:www.)?(?:domain\.com)$
RewriteCond %{HTTPS} on
RewriteRule ^login.php$ http://%{HTTP_HOST}%{REQUEST_URI} [R=302,L]

Finally, a minor hint: never test with 301 enabled, see this answer Tips for debugging .htaccess rewrite rules for details.
