There's no good way to do real-time replay like this, which makes perfect sense when you're dealing with client and server TCP/IP stacks. Your best bet is to clone that traffic off, then replay it afterward. I believe Tea Leaf has this type of functionality, and I'm sure there are others out there as well.

 

 

One thing to note: it's really, really hard to effectively 'replay' at layer 4, because its behavior is very much tied to the actual client and server TCP/IP stacks at that point in time. For example, you may be throttling windows, etc. because other traffic is occupying buffers, bandwidth is an issue, or whatever.

 

 

Just something to think about. Replaying Layer 7 isn't that big a deal at all.
