Hi Matjaz,
As it happens it can do that for you.
In the Project Defines set
NetShowSend=>1
And run Debugview.exe
All the outgoing packets then appear in DebugView (which you can save if you like.)
If that's not good enough, then add your own embed code to the
WebServer procedure, Send method. The outgoing text there is in self.packet.bindata
cheers
Bruce
