they are called on the server each time - I always thought javascript was

or are all of them in the include .js file downloaded for use at the client
end somewhere?
If you're talking about this kind of syntax:
<SCRIPT LANGUAGE="Javascript" SRC="something.js">
Then yes, that's handled by the client-side browser. When the browser
encounters this statement, it issues an HTML request for
"something.js", and interprets it just as if its contents were between
<SCRIPT LANGUAGE="Javascript">
and
</SCRIPT>
tags.
Various server-side processing schemes (ASP, PHP, etc) implement
server-side includes. If you use those, the included file is
transmitted to the client as part of the original request, the client
never knows that the content came from a separate file.
