If I order a Unified Communication Certificate (UCC) through www.instantssl.com
do I need to specify that I need all the domains in the order to be both www and non-www, or will Comodo automatically add the www alias?
If I order:
Will the certificate cover BOTH:
firstdomain.com AND www.firstdomain.com
seconddomain.com AND www.seconddomain.com
Or do I need to include the www domains in my request?
You need not include www sub-domains in the request, rather ensure they're on the order form. Comodo will not automatically add the 'www' on these orders, they need to be explicitly set on the order form.
