display_cached_file() public method

This is most useful for caching images (get_favicon(), etc.), however it works for all cached files. This WILL NOT display ANY file/image/page/whatever, but rather only display what has already been cached by SimplePie.
See also: SimplePie::get_favicon()
public display_cached_file ( str $identifier_url, str $cache_location = './cache', str $cache_extension = 'spc', str $cache_class = 'SimplePie_Cache', str $cache_name_function = 'md5' )
$identifier_url str URL that is used to identify the content. This may or may not be the actual URL of the live content.
$cache_location str Location of SimplePie's cache. Defaults to './cache'.
$cache_extension str The file extension that the file was cached with. Defaults to 'spc'.
$cache_class str Name of the cache-handling class being used in SimplePie. Defaults to 'SimplePie_Cache', and should be left as-is unless you've overloaded the class.
$cache_name_function str Obsolete. Exists for backwards compatibility reasons only.
