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 Content-Type: image/jpeg Content-Length: 14995 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. -- Karl Vogel I don't speak for the USAF or my company For a nosebleed: Put the nose much lower then the body until the heart stops. --submitted to science and health teachers, Jr High thru college -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
