Serving Twitter's JS for Intents or Tweet Button's is a pain when it comes to SSL as Twitter has no SSL Cert installed on their serving subdomain. To get around this, without having to manually maintain the JS, I came up with the following workaround.
Create a file called twitter.platform.js.php in your JS Folder and paste the following:
<?php
header('Content-type: text/javascript');
echo file_get_contents('http://platform.twitter.com/widgets.js');
?>Then, in your index file where you are calling the Twitter JS, replace the Script tags with the following:
<script type="text/javascript" src="/location/to/js/twitter.platform.js.php"></script>The above code will pull Twitter's non-secure JS from their server and render the output as JavaScript and allow you to # serve it over SSL without the warnings, as it will originate from your site.**
