How to prevent subdomains from redirecting to https - htaccess?

Question

I am trying to work out how to redirect all http instances to https:// though excluding the subdomain.

RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^(www\.)?example.co [NC]
RewriteRule (.*) https://example.co/$1 [L,R=301,QSA]

For example, domain.example.co should be left as it is and not redirected to https:// .

example.co or example.co/sub/sub should be redirected to https://

I have tried changing the RewriteRule:

RewriteRule ^$ https://example.co/$1 [R,L]

This leaves subdomains as they are but has no effect on subdirectories under example.co - ie example.co/sub/sub.

How could I redirect from http to https but exclude all subdomains?

Note

I also have a rewrite rule which points subdomains to their directories without changing the URL:

RewriteCond %{HTTP_HOST} ^(.*)\.example\.co [NC]
RewriteRule ^(.*)/?$ http://example.co/%1/$1 [P]

sub.example.co will displays example.co/sub but the URL will not change

Answer 1

You can try this :

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{HTTP_HOST} ^(.+\.)?domain\.com$
RewriteRule ^(.*)$ https://%1domain.com/$1 [R,L]

Or This :

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{HTTP_HOST} ^(www\.)?sub\.domain\.com$
RewriteRule ^(.*)$ https://sub.domain.com/$1 [R,L]

Note: Replace sub with subdomain and domain with domain name

Enjoy it ;-)

Try below I am assuming you are not using www appended to host.

RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^example.co [NC]
RewriteRule ^(.*)$ https://example.co/$1 [L,R=301,QSA]

RewriteCond %{HTTP_HOST} ^(.*)\.example\.co [NC]
RewriteRule ^(.*)/?$ http://example.co/%1/$1 [P]
ProxyPassReverse / http://example.co/
