DLL as `src` of `<script>`

Question

I was browsing the source code of some website, and noticed a dll file being used as the src of a <script>.

(view-source:http://www.yellowbridge.com/onlinelit/baijiaxing.php)

It was something like: <script src="some-dll-file.dll"></script>

Several questions:

• I didn't know a <script> could be anything besides js. What else can it be used for?
• Can you point me in the direction of some more information on this topic? I've tried ggoogling around, but realized that I don't know what I should be googling exactly.
• Is this cross-platform? I mean if I were to try this on epiphany on an ubuntu box, would it function and serve its purpose? I'm on a windows box right now and won't have access to anything else for a while, so I can't test it myself.

Answer 1

Actually the file you are referring to 'yellowbridge.dll' is a javascript file itself. You can view the source of this file.

It might be the dll that generates javascript code.
