I want to setup a Comodo SSL certificate (or another one) for one of my virtual servers. So i search a documentation to learn how to do this? But i can not find any documentation. I find some topic about SSL certificates, but i want to take more detailed and general information about this setup operation.

Can you give how to do this setup operation?

A ssl certificate is really easy to set up.
once you have a domain with ssl, go to 'server configuration' - 'Manage SSL Certificate' and do a signing request

that info you give to your host who will create the certificate. He will send it to you per mail with further instructions.

However the returned certificate is a matter of copy&paste in the section discussed in the first alinea

yes, i understood.

thanks for your answer.
