For static files, either "curl" or "HEAD" can do this. For example:

% curl -I http://www.hcst.net/~vogelke/pictures/2012/0105-new-year-wishes/p04.jpg
HTTP/1.1 200 OK
Date: Tue, 06 Mar 2012 03:49:27 GMT
Server: Apache
Last-Modified: Thu, 05 Jan 2012 20:04:57 GMT
ETag: "414a07-3a93-4b5cd7246ac40"
Accept-Ranges: bytes

A dynamically-generated page will return the current time. Also, the
server may be configured to NOT return the modtime for (say) an
index.html file, even if it's static.
