Cannot overload cache drivers (memcached)

[eluser]CoderBoy[/eluser]
Hey,

How have you actually managed to override the whole driver?

I'm stuck with the same problem you have, I need to prefix the keys and am not going to touch the core CI code.

I've tried all location I can think of for the file

Code:

application/core/MY_Cache_memcached.php
application/libraries/MY_Cache_memcached.php
application/libraries/Cache/Drivers/MY_Cache_memcached.php

with varying class declarations

Code:

class MY_Cache_memcached extends CI_Cache_memcached {
class MY_Cache_memcached extends Cache_memcached {
class MY_Cache_memcached extends CI_Driver {

What combination did you have?

Thanks
