title: Apache SetEnv with special characters
body: <p>I'm trying to set an environment variable in Apache using SetEnv in my vhosts.conf file with the following:</p>
  
  <pre><code>SetEnv FACEBOOK_SECRET 13jf93jjdshut7qpm321b1vv5nod973j10
  SetEnv DATABASE_URL "postgresql://postgres:sdfesf@localhost:5432/public"
  </code></pre>
  
  <p>The FACEBOOK_SECRET environment is showing up in php with the genenv() function, but the DATABASE_URL is empty. I'm assuming it's due to the special characters in the connection string, but I don't know if or how to escape those characters. Any ideas?</p>
