Set expire headers for a list of URI

Hi.

What’s the best way to tell nginx to set expire headers to list of uri?
Like:

www.domain.com/bigscript.js
www.domain.com/weirdfolder/bigstyle.css
www.domain.com/yetanotherfolder/bigjpeg.jpg

I search the forums and I could only find examples for all files
(ico|js|css) and I need the headers only for specific uris.

Cheers!
