Use GET? The basic paradigm involved is that GET should be "safe" for search engines and bots to read and POST is used to "alter" data on the server, so engines and bots should not, in general, crawl through POST. That's a generalization, and probably should be amended to "blindly crawl" as there are obviously a zillion cases where an automated process to do POST operations is the "right answer" Anyway, the browser is assuming that POST data *DID* something on the server, and re-doing that action could be harmful. So it's giving the user the option of re-doing it, or not. If you use GET, the browser "knows" that you expect them to re-visit and it's okay to re-load the page. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
