HTTPS redirect
 

I'm trying to redirect all HTTP traffic to HTTPS. The following within .htaccess works to a point. if abc.com is typed in, the URL correctly converts to https://www.abc.com/vb4/. It does not work when an http link is provided. http://www.abc.com/vb4/showthread.php/123-post comes back as https://www.abc.com/showthread.php/123-post. Note that the vb4 directory is stripped from the URL which results in a 404. Thanks in advance for any assistance.

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://www.abc.com/$1 [R=301,L]

The htaccess rules you posted should work fine.
What happens when you disable those htaccess rules? Does it still happen or does it go to default behavior?

You could try changing (.*) to ^(.*)$, but I dont see why it would fail, unless maybe you have a RewriteBase messing things up in there somewhere.

This was given for my use from server support.

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

Best one for me is:

RewriteEngine On
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

Wow, this RewriteCond %{HTTPS} on
is absolute different than mine. Why so difference?
Do we know what "on" means?
