The browser cache JS resources?

[Joao Batistella]

Hello.

I have a doubt. I'm thinking about including in all my pages the same
javascrip file with the code:
<script language="Javascript1.1" src="js/staticJavascript.jsp"/></script>

This is because I want this file with all javascript code (or including
code) in all pages, even the page doesn't make use of it.

Is this bad? My doubt is if the browser will always request the JS file,
every request or put it in cache.

Thanks,
JP
