Scheme Agnostic Urls
September 28, 2011
Interesting fact I just discovered. It's possible to specify full urls that automatically pick http or https depending on how the current page was delivered. This helps when using CDNs.
Specify a double slash, rather than the whole prefix:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js" type="text/javascript"></script>
This will automatically pick from
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js" type="text/javascript"></script>
or
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js" type="text/javascript"></script>
