Content Security Policy blocking CDN
<p>I am new at coding and I working on making a website using bootstrap framework now I use the bootstrap cdn's for javascript and css but once I put the website on a server it blocks the external links. I tried to insert the cdn's into a meta tag as follows:</p>

<pre><code>    &lt;meta http-equiv="Content-Security-Policy" content="default-src 'self' 
     http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css 
     http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"/&gt;  
</code></pre>

<p>but once put on the server the browser still blocks the scripts.
Can you please tell me what I'm doing wrong. I would like to deal with Content Security Policy inside a hypertext file if possible.</p>
