refresh problem

Hi,

How you prevent / detect users press refresh button. I have a script that insert data on database and every time user refesh, it insert into database ?

Thanks

put a pragma=no-cache tag in the header so that it doesn't cache and expire the page immedaitely. Then redirect the user using a meta-refresh tag. If they hit the back button the page will be expired.

that's one way

Thank you. However, can you give exactly what it look like. Otherwise I have to search again.
