As no code here, so I only raise idea according to my experience =) The possible output for a guest book are : 1. Thank you page 2. The same page as the guest book (but resulting on the process of POST) 3. Redirect to the page same as the guest book(By GET method)
If case no. 1 , you may add another file with log on IP address and sign Time. When a next sign is active, compair the IP and sign time pairs along the log file. So if the sign time and IP are match, and the time difference is shortern than a certain time period, than don't do the sign(write) progress, but returning to some other page. If case no. 2, you better re-write the result process, It's not a good idea anyway. If case no.3, you could make a time comes with the url..... suppose before sign, guest is visiting http://somesite.com/guest.pl?page=0 and after sign, direct to http://somesite.com/guest.pl?page=0&1231203201231 People behavior on RELOAD a page mostly because can't see what they sign. with this, cache will not affecting the result, they must see what they sign. (if no problem with your script) have a nice day =) ----- Original Message ----- From: "Troy May" <[EMAIL PROTECTED]> To: "Beginners CGI List" <[EMAIL PROTECTED]> Sent: Friday, January 04, 2002 3:58 PM Subject: Refreshing a Guest Book type page > Hello, > > I don't have a working example, this is for a friend. > > He says he has a guest book set up on his site.
