+Using HTTP verbs in routes
+==========================
+
+It is possible to use HTTP verbs (request method) to define your routing rules.
+This is particularly useful when building RESTful applications. You can use standard HTTP
+verbs (GET, PUT, POST, DELETE, PATCH) or a custom one such (e.g. PURGE). HTTP verb rules
+are case-insensitive. All you need to do is to add the verb as an array key to your route.
+Example::
+
+ $route['products']['put'] = 'product/insert';
+
+In the above example, a PUT request to URI "products" would call the ``Product::insert()``
+controller method.
+
+::
+
+ $route['products/(:num)']['DELETE'] = 'product/delete/$1';
+
+A DELETE request to URL with "products" as first the segment and a number in the second will be
+mapped to the ``Product::delete()`` method, passing the numeric value as the first parameter.
+
+Using HTTP verbs is of course, optional.

+Step 2: Update your classes file names
+**************************************
+
+Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers
+and models) must be named in a Ucfirst-like manner or in other words - they must
+start with a capital letter.
+
+For example, if you have the following library file:
+
+ application/libraries/mylibrary.php
+
+... then you'll have to rename it to:
+
+ application/libraries/Mylibrary.php
+
+The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
+own libraries and core classes.
+
+ application/libraries/MY_email.php

+The above files should respectively be renamed to the following:

+
+Models:
+
+ application/models/misc_model.php -> application/models/Misc_model.php
+
+Please note that this DOES NOT affect directories, configuration files, views,
+helpers, hooks and anything else - it is only applied to classes.

+You must now follow just one simple rule - class names in Ucfirst and everything else
+in lowercase.

=============
+Redis is an in-memory key-value store which can operate in LRU cache mode.
+To use it, you need Redis server and phpredis PHP extension
+`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
+
+Config options to connect to redis server must be stored in the application/config/redis.php file.
+Available options are::
+
+ $config['socket_type'] = 'tcp'; //`tcp` or `unix`
+ $config['socket'] = '/var/run/redis.sock'; // in case of `unix` socket type
+ $config['host'] = '127.0.0.1';
+ $config['password'] = NULL;
+ $config['port'] = 6379;
+ $config['timeout'] = 0;
+
All of the methods listed above can be accessed without passing a
specific adapter to the driver loader as follows::
$this->load->driver('cache');
$this->cache->redis->save('foo', 'bar', 10);
-.. important:: Redis may require one or more of the following options:
- **host**, **post**, **timeout**, **password**.
