Not nearly as many keystrokes :) The other 237 times I've answered this question, the reader doesn't understand *WHY* they can't do that unless it's broken down into a slow-motion instant replay of server-side versus client-side. And if they don't understand *THAT*, they are going to have troubles down the road with Cookies, HTTP Authentication, scraping from SSL sites, sessions, and probably a couple other PHP topics. I'd rather get them thinking about this now than answer a dozen more questions all stemming from a fundamental lack of understanding of the interaction of browser, server, and PHP. YMMV I know *I* didn't get this until somebody was kind enough to build a diagram of what happens in an HTTP exchange. It's in the archives (about 6 years back, mind you...) So I typed Jim, Bob and "" a lot, and a couple extra lines for fun. [shrug] I type fast anyway. :-) -- 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
