Apache代理到Tomcat强制SSL

Question

My application is hosted in AWS. It has Apache proxying to tomcat. SSL is terminated at the Elastic Load Balancer, and all traffic is offloaded to port 80.

My need is to have all requests to the site be redirected to SSL. I've been doing a lot of reading about mod_rewrite and have experimented with various solutions I've found on the web, but have not been able to make this work.

To be clear, Apache is successfully proxying requests to Tomcat. It's the redirection to HTTPS that I'm stuck on. Any suggestions would be welcome.

Answer 1

Try with the X-Forwarded-Proto header, eg:

<VirtualHost *:80>
    ...
    RewriteEngine On
    RewriteCond %{HTTP:X-Forwarded-Proto} !https
    RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R=permanent]
    ...
</VirtualHost>
