Do I really need 2 SSL certifications to redirect a naked domain to www?
<p>I have a website, which I only want to be used with the <a href="https://www-prefix" rel="nofollow">https://www-prefix</a>. 
I have to 2 url-redirects configured in my web.config (asp.net MVC on Azure websites), one from http to https, and one from naked domain to www.domain.</p>

<p>I initially bought an SSL certificate for my www.domain.com only, but then when someone would enter the naked domain, he would get a browser warning/block before the redirect could even happen. Eventually I bought a 2nd SSL cert. for my naked domain as well and it all works now, but I can't help wonder, do I really need to buy 2 certificates for this scenario?</p>
