title: Customizing Google + Share Text (snippet)
body: <p>I'm creating an online HTML5/Javascript Quiz. I'm sharing the results of the Quiz through Facebook and Twitter. The messaging is created via Javascript, "I just got X out of Y questions correct"</p>
  
  <p>I want to do the same with Google Plus. However, it appears that the "snippet" is generated by the schema.org, Open Graph, or Title/Description tags on the page. Documentation here: <a href="https://developers.google.com/+/plugins/snippet/" rel="nofollow">https://developers.google.com/+/plugins/snippet/</a></p>
  
  <p>I thought I could just dynamically generate these tags via query string parameters in PHP, but it looks like Google caches the page. Any ideas?</p>
  
  <p>PHP:</p>
  
  <pre><code>&lt;?php 
  $correct = strval($_GET['correct']);
  $title = "I took the Quiz and answered " . $correct . " of 9 questions correctly.";
  ?&gt;
  &lt;!DOCTYPE html&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;&lt;?php echo($title); ?&gt;&lt;/title&gt;
          &lt;meta property="og:title" content="&lt;?php echo($title); ?&gt;" /&gt;
      &lt;/head&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I dynamically create the url .../share.php?correct=4</p>
  
  <p>But when I share the page, I see the message:</p>
  
  <pre><code>I took the Quiz and answered of 9 questions correctly.
  </code></pre>
  
  <p>It doesn't appear to be displaying the dynamic data. I'm assuming because Google has cached the page?</p>
  
  <p>Thanks</p>
