I am on windows server 2003 and I have a CGI site that uses a DLL file called account.dll

I want to secure call to one page only so I followed the steps about adding new certificate and I have only the option "send it later" active

so I have now a text file contain the certificate request, my question:

- now do I send this request file to my host company to obtain a certificate ?
- I know that to secure one page I right click on account.dll and choose properties for that file but what is the options I must use to configure this file for HTTPS ?
