Javascript file link is encrypted?

[nguyenxh]

Hi,

Once time, I went to a website in which there is a very nice javascript effect. I tried to view page source and the javascript source code:

For example it is like this:

<script src="/javascripts/effect_36ec00767605b72c53de91adb0a803ab240bded4.js?1230496318" type="text/javascript"></script>

I already make the following attempts to download the javascript file:

1. http://domain.com/javascripts/effect_36ec00767605b72c53de91adb0a803ab240bded4.js?1230496318

2. http://domain.com//javascripts/effect.js

But there is no way successfully!!!

Do you have any idea how could I do so?

Thanks in advance.
