Subject [users@httpd] SetEnv HTTPS on... not working.
Date Fri, 10 Dec 2010 00:31:55 GMT
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.


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?



Best regards,
Margus Pärt
