Tip #33   Because wireshark is big and nc is small.

mknod backpipe p; while nc -l -p 80 0<backpipe | tee -a inflow | \
nc localhost 81 | tee -a outflow 1>backpipe; do echo \"restarting\"; done


Listen on localhost:80, forward to localhost:81 and log both sides of the conversation to outflow, automatically restarting if the connection dies.
