So, you're saying I should still be able to use the original cert I purchased from DH somehow? Isn't there server information and IP address embedded in the SSL certificate?
Okay, first of all, it's not a cPanel. It's a very crude no-frills control panel. The reason I had to go with them was because I am resurrecting a ColdFusion Web site from someone who abandoned ours. But we can't take it over at the same Web host because the domain name still exists on that server and the host will not remove it because the account it's under is still live with other domains. I found that there are not many decent ColdFusion hosts at a reasonable price. These guys are. In fact, they've been very helpful getting some previously hard-coded CF hacks to work on their server using mod-rewrites. And, they told me they don't sell shared cert's so it would cost me $149 if they ordered a cert for me, but suggested I just get one from GoDaddy (whom I despise). I thought I could get it from DH since their panel says you can purchase a cert even if your domain is not hosted at DH. I have 5 other domains hosted here at DH so I figured it was easiest to get the cert here too. AFAIK, the host for my other domain is using Tomcat under IIS - does that make sense? That's what they said. I thought Tomcat was for Linux. Anyway, they've now given me a CSR but there doesn't seem to be anywhere to enter it in the Comodo order form.
I am grateful to the info you guys are providing. I have never had to purchase a cert' from somewhere other than the Web host for a particular domain.
