PHP - Caching JavaScript

Question

I have a php file, content.php, which includes a another php file, viedo.php. Inside video.php i use a script tag to do some javascript stuff for displaying a video. I was wondering if i were to put the script into an external javascript file, would that file be cachable, and if so, is this bad/good practice? My thinking is, since php builds the page when you navigate to the url, im not sure if the browser will be able to tell if the javscipt file was cached.

content.php

<?php
include 'nav.php';
 // ...
include 'video.php';
 // ...
php include 'footer.php';
?>

video.php

<div>
<div id="myDiv">This text will be replaced with a player.</div>
<script>
jwplayer("myDiv").setup({
    "file": "http://example.com/myVideo.mp4",
    "image": "http://example.com/myImage.png",
    "height": 360,
    "width": 640
});
</script>
</div>

It's always better to place all javascript that can be cached in external files. The browser caches external files unless you send specific heathers so that the content would notbe cached. — jeprubio

We don't know the overall architecture of your app but the browser doesn't care about file extensions (plus they can be easily hidden anyway). — Álvaro González

If that's all the JavaScript you're going to be using, there's minimal benefit to caching it, and the extra HTTP request for the .js file is likely to set you back more than you gain. — ceejayoz
