/**
|

|
|
* Humble HTTP Agent extension for SimplePie_File
|
||
|
|
*
|
||
|
|
* This class is designed to extend and override SimplePie_File
|
||
|
|
* in order to prevent duplicate HTTP requests being sent out.
|
||
|
|
* The idea is to initialise an instance of Humble HTTP Agent
|
||
|
|
* and attach it, to a static class variable, of this class.
|
||
|
|
* SimplePie will then automatically initialise this class
|
