165 * Type | Setting | Description | Default Value
166 * ----------|------------|------------------------------------------------|---------------
167 * `string` | base_url | The base URL for your application. This should be the *relative* path from your DOCROOT to your `index.php` file, in other words, if Kohana is in a subfolder, set this to the subfolder name, otherwise leave it as the default. **The leading slash is required**, trailing slash is optional. | `"/"`
168 * `string` | index_file | The name of the [front controller](http://en.wikipedia.org/wiki/Front_Controller_pattern). This is used by Kohana to generate relative urls like [HTML::anchor()] and [URL::base()]. This is usually `index.php`. To [remove index.php from your urls](tutorials/clean-urls), set this to `FALSE`. | `"index.php"`
169 * `string` | charset | Character set used for all input and output | `"utf-8"`
170 * `string` | cache_dir | Kohana's cache directory. Used by [Kohana::cache] for simple internal caching, like [Fragments](kohana/fragments) and **\[caching database queries](this should link somewhere)**. This has nothing to do with the [Cache module](cache). | `APPPATH."cache"`
171 * `integer` | cache_life | Lifetime, in seconds, of items cached by [Kohana::cache] | `60`
172 * `boolean` | errors | Should Kohana catch PHP errors and uncaught Exceptions and show the `error_view`. See [Error Handling](kohana/errors) for more info. <br /> <br /> Recommended setting: `TRUE` while developing, `FALSE` on production servers. | `TRUE`
173 * `boolean` | profile | Whether to enable the [Profiler](kohana/profiling). <br /> <br />Recommended setting: `TRUE` while developing, `FALSE` on production servers. | `TRUE`
174 * `boolean` | caching | Cache file locations to speed up [Kohana::find_file]. This has nothing to do with [Kohana::cache], [Fragments](kohana/fragments) or the [Cache module](cache). <br /> <br /> Recommended setting: `FALSE` while developing, `TRUE` on production servers. | `FALSE`
