Force SSL/HTTPS with Zend Framework and mod_rewrite

Question

I have a Zend Framework application that I want to force into HTTPS using mod_rewrite. I am pretty lost when it comes to mod_rewrite. Here is my current .htaccess file in the root of my application.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule !\.(html|htm|php|js|ico|gif|jpg|png|css|csv)$ /subdir/index.php

What is the best way to force the application into HTTPS based on what I have? I have tried a couple of the examples I found on here, but I keep getting redirect loops or internal server errors when I try them.

Thanks for your help!

Answer 1

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^.*$ https://mydomain.com/\0 [L,QSA,R=301]

Answer 2

Put this rule before your current rules:

RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
