Redirecting http subdomain to https subdomain

[afridy]

Hello,

i have code to redirect http://www.yoursite.com to https://www.yoursite.com

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.fancyblue.net/$1 [R,L]

but i need to modify the above code to redirect

http://mail.yoursite.com to https://mail.yoursite.com

Please help.

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

Untested, but I think this will do the trick. There’s a rewrite condition now that exists purely for the purpose of capturing the subdomain value, then we use that captured value (%1) in the rewrite.

afridy,

Jeff’s code will capture EVERY subdomain and force https. Since you only want to redirect the mail subdomain, specify mail.

RewriteEngine on RewriteCond %{SERVER_PORT} ^80$ RewriteCond %{HTTP_HOST} ^mail\.fancyblue\.net$ [NC] RewriteRule .? https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

The differrences are:

1. Specify port 80 not any port containing 80 as digits in the port number.
2. Specify mail.fancyblue.net using No Case.
3. If both conditions are met, redirect the {REQUEST_URI} to the secure server without duplicating Apache variables for {HTTP_HOST} and {REQUEST_URI}; any query string will not be affected.

Regards,

DK
