Identify Remote User

[nandina]

Hi there

How do you extract the 'Volume Serial Number' of the drive of a remote user submitting a form, and include it in the returned form data ?

OR

Is there any unique data that can be obtained using javascript to recognise a remote machine submitting a form, other than IP address ?

Problem: we have a free service being exploited by opportunists who are submitting forms and charging for the information returned. We need to recognize these very frequent users. Unfortunately, the conventional log-on authentication can not be used in this application. The form uses PHP - can javascript help client-side ? Any ideas ?

hi nandina,

sorry, javascript cannot access info like logon user or drive name.

however, you might be able to control this by checking for document.referrer before allowing the form to process...if the page was arrived at by typing in the url, document.referrer will be empty, else it will contain the url of the page they came from. just check to make sure it's yours
