Sometimes the developer knows how stale information can get before it needs to be refreshed. An awful lot of pages fetched with GET args are just straight-up retrievals from mostly-static databases, and can be cached with impunity. Also, there are other types of caching. On a multi-use machine that is busy with other stuff but not getting a lot of web traffic, httpd may have been paged out. And the PHP source file will be cached by the filesystem for a while after being read, saving subsequent repeat visits the delay of a disk operation. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
