actually i want to record the data that outgoing at my network then resend them for example in yahoo A person send a message to B person then A person record the data with X program and close the yahoo at the end the A person send the data has been recorded by X program and B person receives exactly the data received before is it possible? or not?
actually it is not possible because there is many concept in any data transfer to server. one of that is freshness that mean we use some data like date for check a message and if this data is duplicate, then the pm block. and many mechanism for blocking duplicate message
