Hey all, I got a problem, validating the double submit, I want to do it not with javascript, but with the servlets (server side). I am doing the following, I store in a session variable the time in seconds when the last transaction occured, every time I make the same transaction again I compare the actual time with the time in the session variable that I stored previously. If the time difference is less than 6 seconds and the information that the user input is the same that the previous transaction then I dont process the request. The problem is that the range of time varies upon the response time of the sistem, wich depends upon how many people are connected, then I dont see that this range coud be reliable, can somebody give any detailed idea of how can I validate this double submit, from the server side?. For your help, I thank you in advance bye Lorena Carlo =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
