I have SSL offloader, what checks wheather user came using HTTP or HTTPS (sends accordingly header.)

As I want it to be transparent to application and available to .htaccess, I use apaches values. I want to overwrite them.

Hello!

I have SSL offloader sending HTTPS header to backend server.

In backend server I have:
SetEnvIf HTTPS "(..*)" HTTPS=$1
RewriteCond %{HTTPS} !=on
RewriteRule (.*)      https://%{HTTP_HOST}%{REQUEST_URI}?%{HTTPS}
[L,R=301]

And it causes infinite redirect loop (to https://server/url/?off),
because env value HTTPS is "off" for RewriteCond.


I also tried:
SetEnv HTTPS on
RewriteCond %{HTTPS} !=on
RewriteRule (.*)      https://%{HTTP_HOST}%{REQUEST_URI}?%{HTTPS}
[L,R=301]

But it also created infinite loop - HTTPS was shown to be off.
http://wiki.apache.org/httpd/RewriteLooping

If I watch HTTPS env value from some script (eg PHP $_SERVER['HTTPS']
is
"on"), then from there it is shown "on".



I got it woking so:
RewriteCond %{HTTP:HTTPS} !=on
RewriteRule (.*)      https://%{HTTP_HOST}%{REQUEST_URI}?%{HTTPS}
[L,R=301]

But I would like, if it would not check header, but env value. Could
anyone clarify, why it works so, or throw some good link please?

Somehow I fail to see what problem you're trying to solve.
