/*
Code to test the webserver. This depends on:
- The cat images being available, for concurrent espfs testing
- the test.cgi script available, for generic data mangling tests


This test does a max of 4 requests in parallel. The nonos SDK supports a max of
5 connections; the default libesphttpd setting is 4 sockets at a time. Unfortunately,
the nonos sdk just closes all sockets opened after the available sockets are opened,
instead of queueing them until a socket frees up.
