Is a *.html source file containing <script>...</script> supposed to work?

I added a `foo.html` containing

    <body><script type="text/javascript" src="http://friendfeed.com/embed/widget/..."></script></body>

after normal build when I visit `http://foobar.com/foo/` it gives me a normal page with head and footnote texts but empty body
    <div id="pagebody"> 
    <div id="content"> 
    </div> 
    </div> 

Any ideas how this could/should work?
