Cache in kohan, how to use caching in kohan?

Question

Kohana

Hello, how to enable or connect the cache in Kohan?
Kohana version 3.1

Answer 1

1. Include the module in bootstrap.php
2. Initialization $cache = Cache::instance();
3. Add something to the cache $cache->set('foo', 'bar', 1800)(add bar to the cache for 1800 sec.)
4. Get something from the cache $cache->get('foo')
kohanaframework.org/3.3/guide/cache/usage SQl
caching -requests (we cache the result for 1800 seconds):
Route caching:

if ( ! Route::cache())
{
    // Роуты

    if (Kohana::$environment === Kohana::PRODUCTION)
        Route::cache(true);
}

Answer 2

Added caching of routes, it seems to work, it does not write errors.

if ( ! Route::cache())
{
    // Роуты

    if (Kohana::$environment === Kohana::PRODUCTION)
        Route::cache(true);
}

I completed the first and second points, but 3 and 4 I don’t understand where to do this, where to add that.
3. Add something to the cache $cache->set('foo', 'bar', 1800)(add bar to the cache for 1800 sec.)
4. Get something from the cache $cache->get('foo')
SQl query caching (caching the result for 1800 seconds):
in the bootstrap at the very bottom I found something else, though I don’t understand what it is.

$version = 'new';
if (UTF8::stristr($_SERVER["HTTP_USER_AGENT"], "MSIE")){

    elseif(UTF8::stristr($_SERVER["HTTP_USER_AGENT"], "MSIE 7.0")) $version = 'ie';
