>>>>Thank you (and Viv). For me it is important to log the IP of a user who submits within several seconds. Basically I am troubleshooting the following issue. Users submits duplicate orders by Submitting and then clicking on Back and Submitting again. They claim that they don't do it. And the only way I can prove to them (and to myself) is by logging every Submit with the IP and order number. So two submits within seconds with the consecutive order numbers and the same "IP" will show the trend.

>>>You should probably protect yourself by not allowing that to happen in the first place - or at least make it difficult.
>>>You could, for example, disable the submit button (and change the text to 'Please Wait' or somesuch) then, when the order is successfully submitted, clear the order details before re-enabling the button.

>>I thought about something like this but so far I cannot come up with anything practical. When the Order Page is called, it is not "known" if the user brings it up for the first time or by Back from the Order Acknowledgement page. And since the issue has not been a big problem (most customers understand that Back is not a good thing), I have not spent the time to implement it. I think by showing the users that they are doing it, it will help.
>>Thank you.

>Re-submitting by first using the 'Back' button does imply a certain contrariness on the users part :-}
>You can't prevent it completely but there are a few tricks that make it difficult. Google 'Disable Back Button' for some suggestions.
