rewrite for subdomain to SSL?

Hello,

I’m looking to enforce SSL access to a subdomain using a rewrite rule. When users visit http://subdomain.domain.com/* the rewrite rule should point the user at httpS://subdomain.domain.com/*

I’ve looked at the following rule, which works across the whole site, but I’m not familiar with the syntax to modify it for a subdomain only.

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Any help appreciated,

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(www\.)?subdomain.domain.com
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Hi ravenpl,

Thanks for the answer. I've tried both of the following and both work; whats the difference in the last line?

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(www\.)?subdomain.domain.com
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(www\.)?subdomain.domain.com
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R]

Thanks,

L - means don't try next rewriteRules on this result
R - means don't rewrite, but redirect(301 response code is sent to client) - I guess it's default if protocols/ports do not match...
