Use this form to submit a request for a server certificate. You must submit
  a PKCS #10 request. If you have a Netscape server, create a PKCS#10 request 
  by using the Netscape Administration Server instance associated with the 
  server for which you are requesting the certificate. In the Netscape 
  Administration Server forms, choose Encryption, then Request Server Certificate.
 
  If you are not using a Netscape server, follow the appropriate steps to 
  generate a PKCS #10 request with the server you have. 
  After you click the Submit button, your request will be submitted to 
  an issuing agent for approval. You will receive the certificate in email
  when it has been approved.
