Redmine

I searched the bugs on redmine.org and found #157 which seems to have related effects but for emails.

This is all based on your Apache settings. The "protocol" and "hostname" in the administration setting are only for email. Check to make sure you have your Apache with the following line:

  RequestHeader set X_FORWARDED_PROTO 'https'

That tells Redmine and mongrel that https is used.

Full configuration file from my old Apache:

<VirtualHost *:80> 
  ServerName projects.littlestreamsoftware.com

  RewriteEngine On

  # Redirect any non HTTPS requests to the HTTPS server
  RewriteCond %{HTTP_HOST} ^projects.littlestreamsoftware.com$ [NC]
  RewriteRule ^(.*)$ https://projects.littlestreamsoftware.com$1 [R=301,L]

  Include /etc/apache2/common/hide-svn
  Include /etc/apache2/common/deflate

</VirtualHost>

NameVirtualHost *:443
<VirtualHost *:443>
  SSLEngine on
  SSLCertificateFile /etc/apache2/apache.pem

Well,
it looks like the problem was in the configuration of my server. All is working now.

The solution described by Eric Davis in reply No. 2 fixes my problem - it's working now :)
