Advice needed for SSL certs

[Gambit]

Hi,

I hope someone here can help me as I can't seem to find definitive info on my question.

If I have an e-commerce site at "www.domain.com" and I have an ssl cert for this domain and decide I need to run a second server located at "images.domain.com" that just supplies images during the checkout process. Unless the images server is also running ssl then you will obviously get the warning from the browser about some content not being secure.

If I run the images server with ssl I will need to get another cert for this server. If I'm running 2 different certs will all browsers recognise the site as secure or is there something special that needs to be done when acquiring the second cert?

I see you can get wildcard certs and UCC certs as well. Would I need one of these certs or is just buying a normal domain cert fine here?

Thanks.

make sure you get a cert for *.domain.com from the issuer and then you install that cert on all servers in your domain. You don't have to do anything special.

you'll need one SSL for every domain that you want to secure, even if it's a subdomain. So get 2 SSL certs.

When you have more than 5 or 6 (just check the prices) subdomains to secure, then you can look at a wildcard SSL, which will secure all the subdomains of, and including the main domain, for example mydomain.com, shop.mydomain, images.mydomain.com, customer.mydomain.com, etc.
