This is less a specific VB question and more a "how would you go about this" type of question. I have been tasked with building a tool for our QA team that replicates data activity from a given application. If I packet sniff the application like CommView or Ethereal I can see the data being sent to the server and vice versa, but my question is in how to replicate it.

I realize the data may be encrypted, but it seems apparent that I should be able to send the identical encrypted string and receive the same response (in encrypted form). I am just unclear where to begin as this is new to me. Looking at the packet sniffer I see text data, hex data, etc but what do I send to the server in order to replicate this?

Thanks to anyone with ideas, prior experience, etc.
