Troubleshooting and identifying problems on the wire

Sometimes the interaction between the client and the server fails, and the reason for such failures often requires analysis; otherwise, their root cause stays unknown. We spotted that our client application does not load and thus doesn't display data for an existing item. Let's try to investigate the root cause for that by setting up an http tunnel between the client and the server. This will be a kind of MiM (man-in-the-middle)-based investigation, as we will listen to one port and redirect the incoming request to another, to see whether the server returns correct responses or its pipe gets broken somewhere in the middle. There are various TCP tunnels available out there; I have been using a simple open source one available on GitHub at https://github.com/vakuum/tcptunnel. Its author also maintains a separate website where you can download prebuilt binaries for the most common operating system; they are available at http://www.vakuumverpackt...
