Identifying an individual file in the cache

[eluser]GSV Sleeper Service[/eluser]
the cache filename is an md5 sum, see Output.php in the system/libraries folder to see how it works, but basically it's

Code:

$uri =    $CI->config->item('base_url').
    $CI->config->item('index_page').
    $CI->uri->uri_string();
$cache_path .= md5($uri);

so you should be able to determine what cache file to delete by rebuilding $uri and finding the md5sum
