is it possible to set custom headers on js <script> requests?

Is something like this possible?

<script src="http://myserver.com/some.js" my-custom-header="foo"></script>

Update (a bit more detail):

I've been asked if there was a way to communicate some parameters to the server as part of the script request using headers instead of GET params. I said, "no," but thought I'd double check.

Short answer: no. By default a script tag will just retrieve the resource specified in the src attribute.

However, if you use an AJAX request to retrieve the script (and add it later/execute it), you can use the setRequestHeader function of the XMLHttpRequest object (see http://www.developertutorials.com/learn-ajax/custom-http-headers-2643.php).

You could also use more complex methods, such as using mod_rewrite to rewrite paths, and include the parameters in the url. The best solution depends on what you want to do, and how much control you have over the server.

No. You'll need to set the headers on the server that's serving up the JS file.

EDIT: I misinterpreted what you meant, it turns out you wanted to set a request header, not a response header. This is still not possible (from HTML) as far as I know.
