As appears to be the usual case with php, I have found that I was doing things the HARD way. While an auto_prepend will work, there is a Apache specific ini setting that will turn on automatic generation of the Last-Modified AND ETAG headers! If you change the default value for "last_modified" to on in your php.in or add the following to your .htaccess file, php will generate both a default Last-Modified header AND an ETAG: php_flag last_modified on Anyone care to comment on whether or not there is a down side to having an etag on a dynamic page related to search engines (or caches for that matter).... Here is the link - NOTE that the docs do NOT mention the ETAG, but my testing is that this ini change also enables that functionality as well! http://us3.php.net/manual/en/ref.apache.php
