How to create “channel.html” file for Facebook SDK
channel, facebook
Solution
Channel file is supposed to have only the code as you've already mentioned
<script src="//connect.facebook.net/en_US/all.js"></script>
You can put caching code anywhere and most probably it is put in the index file.
Problem
In its document, Facebook recommend using a channel file for its JavaScript SDK. My question concerns a small detail about how to create this file. It is clear I must create and HTML file with the line `<script src="//connect.facebook.net/en_US/all.js"></script>` But then Facebook recommend caching this file as long as possible and offers a PHP script to do it. My question is: where should I put this script? In the same `channel.html` file which I will place in the root of my website installation (a self-hosted Wordpress blog). Thanks! P.
