title: install www and non-www ssl cert apache
body: <p>My site (prestashop based) has a certificate for the domain name without the www. After receiving complaints from a client, we wanted to add a certificate for the www.</p>
  
  <p>We are running Apache. What is the best way to install the second cert we just bought? Is it possible to install 2 certificates on Apache for the different host variations, or should I buy a third wild card cert?</p>
  
  <p>Is it possible to easily manipulate prestashop to use the canonical name, i.e. redirect all links to the www version?</p>
