How do I enable file caching?

[ChemicalKicks]

So the obvious question what would you recommend adding to the config to enable caching?

To forestall any issues related to upgrading, you must use the full file path or you'll receive an error.

Thanks to everyone, got file caching working on my test server XF 1.1 now.
Do we have to empty the files in the /cache folder from time to time?

I have created a cache directory in internal_data/cache and chmod 777

is code correct

$config['cache']['enabled'] = true;

$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] = array('cache_dir'  => '/usr/home/w****/public_html/community/internal_data/cache');

$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array('caching'  =>  true,
                                            'automatic_serialization' => true,
                                            'lifetime'    => 1800);

and is it to be inserted into library/config

Any issues using this if i am on a cdn

I wouldn't normally recommend bothering with the file cache unless you have a particular reason for it -- depending on server configs, just not using it can be better.

But that should work and there won't be any CDN issues.
