Hi,

I am using the Post method to submit my form to a Servlet. I am also using
hidden variables to set certain values that I get and interpret in my
servlet.

e.g.,

function undoData()
{
    document.Form.hdFlagAction.value = "0";
    document.Form.hdAuditId = "1234
    document.Form.method = 'POST';
    document.Form.action = "/NASApp/wisper/AuAuditorsSrv";
    document.Form.submit();
}

Now, all that is displayed in the URL is,
http://157.227.15.228/NASApp/wisper/AuAuditorsSrv

But, if the user just changes teh URL, e.g., makes it
http://157.227.15.228/NASApp/wisper/AuAuditorsSrv?hdAuditId=1007, he can
see
the details of the AuditId 1007, though, since this wasn't his audit, he
shouldn't have been able to see these details.

Can anyone please help me and let me know, if I can do something in my
servlet to ignore all that the user enters in the URL ?

Regards,
Vibha
