title: Calling a Javascript function via ssl
body: <p>Please excuse any ignorance on my part, I am very new to SSL and Javascript, so what I am asking may be obvious.  I have tried to Google but can't seem to find the answer to my question.</p>
  
  <p><strong>Background</strong></p>
  
  <p>Basically, I have a website, with a subdomain that holds a rental car booking engine in an iframe, which is called from an external location using Javascript.  We recently moved to SSL and now the booking engine does not display as it is deemed unsecure by web browsers.</p>
  
  <p>I contacted the company that manages the booking engine and they advised that I needed an SSL for the subdomain, which they can load at their end as well (I bought a single domain, not a wildcard, my mistake), and I needed to purchase a static IP on their server. They sent me a quote for €130 per year for and a static IP.</p>
  
  <p>My very limited knowledge of SSL seems to suggest that a static IP is not required, however I am probably wrong about this. </p>
  
  <p><strong>Question</strong></p>
  
  <p>Do I need the static IP for the SSL to work, or will the wildcard SSL resolve the issue?</p>
  
  <p>I understand that the SSL for the subdomain is required, I just can't find an answer for the static IP.</p>
  
  <p>Basically, I don't fully trust the company as they have tried to add unnecessary charges to invoices in the past.</p>
  
  <p>Thanks in advance</p>
