Simple GET example
$response = Invoke-RestMethod 'http://example.com/api/people'
# assuming the response was in this format { "items": [] }
# we can now extract the child people like this
$people = $response.items
GET with custom headers example
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("X-DATE", '9/29/2014')
$headers.Add("X-SIGNATURE", '234j123l4kl23j41l23k4j')

Summary:
Run tcpdump on a pod and then see that information through Wireshark locally on my machine.

Topology
--------
[laptop with wireshark] ------> [AKS Node] ------> [POD (tcpdump is here)]. 

##1. Create the fifo on your local machine (where wireshark will run)
   ```
   mkfifo /tmp/remote-capture.fifo
