disableCache() public ¶
disableCache( )

flash() public ¶
flash( string $message , mixed $url , integer $pause = 1 , string $layout = 'flash' )

Queries & sets valid HTTP response codes & messages.
Parameters
- mixed $code optional null
If $code is an integer, then the corresponding code/message is returned if it exists, null if it does not exist. If $code is an array, then the 'code' and 'message' keys of each nested array are added to the default HTTP codes. Example:
httpCodes(404); // returns array(404 => 'Not Found') httpCodes(array( 701 => 'Unicorn Moved', 800 => 'Unexpected Minotaur' )); // sets these new values, and returns true
