Some of the systems communicating with DCO do not support https communication.
Http communication must be enabled on DCO 8.0 for you to be able to use DCO with these systems, like Data Center Operation: Mobile, Portal, and Data Center Operation: PRO Pack.To handle this, a setting to disable redirecting http to https has been introduced in the server management interface (Webmin).
Use this option with caution and be aware of the reduction in security since your data will no longer be encrypted!
Unless you have enabled a secure connection in the DCO desktop and web clients, disabling the redirection will also mean your communication between the server and clients may be at risk.
