2/**
3 * Humble HTTP Agent extension for SimplePie_File
4 *
5 * This class is designed to extend and override SimplePie_File
6 * in order to prevent duplicate HTTP requests being sent out.
7 * The idea is to initialise an instance of Humble HTTP Agent
8 * and attach it, to a static class variable, of this class.
9 * SimplePie will then automatically initialise this class
10 *
