This file extends the functionality of CodeIgniter's core output library to better manage cached paths. This has been tested with CodeIgniter 2.1.0.
##Installation
Copy the MY_Output.php file to your application/core folder. Assuming your config is still set to use the default 'MY_' prefix for library extensions, the library will be automatically loaded. If not, you will need to amend the MY_Output.php file name and class name appropriately.
##Clearing a cached path
To clear a cache file for a specific URI path use:
$this->output->clear_path_cache($uri);
This will return TRUE if successfull, FALSE if not.
##Clearing all cache
To clear the cache for all URI paths use:
$this->output->clear_all_cache();
##Checking to see if a path is cached
You can check to see if a specific path is cached already by using:
$this->output->path_cached($uri);
This will return TRUE if the path is already cached, FALSE if not.
##Checking the expiration time of a cached path
You can check to see when a cache file is set to expire by using:
$this->output->get_path_cache_expiration($uri);
This will return the unix timestamp (as an int) of the expiration or FALSE if the cache file does not exist.
