Regarding the 20071101 note of "root at mantoru dot de":



That solution got me started but didn't quite work for me. Apache (at least 2.x) applies an algorithm to the Last-Modified time. A solution that worked perfectly for me is at http://us3.php.net/manual/en/function.fileinode.php#78264.

An Apache-like ETag can be generated like this:



<?php

function etag($filename, $quote = true) {

    if (!file_exists($filename) || !($info = stat($filename))) {

        return false;

    }

    $q = ($quote) ? '"' : '';

    return sprintf("$q%x-%x-%x$q", $info['ino'], $info['size'], $info['mtime']);

}

?>
