We launched an ecommerce site a while back and got an ssl certificate for https://www.mysite.com. The site was abandoned for a while, and then recently resurrected. We got a new ssl certificate, but this time it was for https://mysite.com. Now, when people find the site on Google, the url is for https://www.mysite.com, and gives an untrusted site warning.
After some digging I've learned that I can't just redirect https://www.mysite.com to https://mysite.com without having a different ssl certificate for the www version. Is there a way I can correct this problem without having to buy another certificate?
