Comment 5 for bug 1246732

Actually, rather than commenting out stanzas, one should just fix the directives to use the correct statement in the sogo.conf:

<Directory /usr/lib/GNUstep/SOGo>
    Require all granted

    # Explicitly allow caching of static content to avoid browser specific behavior.
    # A resource's URL MUST change in order to have the client load the new version.
    <IfModule expires_module>
      ExpiresActive On
      ExpiresDefault "access plus 1 year"
    </IfModule>
</Directory>

This seems to work the way the distributed file did, but with Apache 2.4. The file does need customisation by the end user, but it would be a nice courtesy to drop a copy in /etc/apache/confs-available so the user doesn't have to go hunting far for the file.
