mod_cloudflare support in Apache
 

Hi,

The 4MLinux website uses Cloudflare, which is now very popular. Their services (DNS+catching) are very good, but there is one inconvenience: your server may be unable to log visitors' real IPs. The solution of the problem can be found here:

The 4MLinux Server 26 (and later) comes with mod_cloudflare available out of the box. However, you must enable it in Apache configuration file.

I don't know much about 4MLinux, but for apache in general:
Make sure that the module is loaded, i.e. make sure that the "LoadModule ..." line used to load mod_clouflare.so is not commented out.
To verify that the module is loaded you can run:
