Protecting Javascript source with PHP

[freebie]

I was wondering if it's possible to prevent javascript access and prevent javascript caching using PHP. My idea is to hide "proprietary" javascript (I know it's hard to make 100%) using PHP like such:
<script langauge='Javascript' src="myjavascript.php?">

and then maybe check the referer server variable to see if the referer was that web page, and only return the script if it is?

Has anyone ever done something like this?

Thanks for any thoughts.

Hrmm...soo.....you double post, which is bad enough, but your posts are about using open source to protect your proprietary code....good luck with that.

Would not work sorry.

You see, any client could just get the page source, get the:
<script langauge='Javascript' src="myjavascript.php?">

then access:
http://www.yourdomain.com/myjavascript.php

This would allow them to see the JS just like normal, as all the myjavascript.php script is doing is outputting it like normal.

hello,

it is impossible to hide something from the user when he is able to download it and use the script in his/her browser. You are wasting your time.
