UDP / TCP / Rest Network Test Utility

A network utility app that supports three (3) modes of operation (TCP, UDP, REST) :

1) UDP Mode

Allows you to send UDP datagrams to another client (perhaps to another instance of this application running on another iPhone) or allows you to just listen for UDP packets. Also, allows you to specify the local port to bind to.

2) TCP Mode

TCP Mode supports two (2) submodes: 1) TCP Client and TCP Server. TCP Client allows you to to connect to a TCP Server via specifying the remote host and port the server is operating on. Once connected, messages can be sent to the server; any responses will be displayed in the output view. 2) TCP Server allows you to create an instance of a tcp server operating on a port that is user configurable. Once one or more clients connect, messages can be sent to the set of connected clients. All responses from the client will be displayed in the output view.

3) REST

REST mode supports three (3) request methods: GET, POST, PUT. In 'GET' mode, given a url, will display the output in output view. In 'POST' and 'PUT' mode, given a url and a body (e.g. parameters), the output will be displayed in the output view. In all cases, the output can be formatted in RAW or JSON.
