Improve Cache Query String behaviour
Typically, in most cases, we do not need to cache all the Query String variables. That's why I suggest to improve `Cache Include Query String` behaviour — allow the developer to independently specify which variables should be cached. For example, consider a query to the following URL address: http://site.com/search?q=query&page=2&session=abcd&utm_source=web In this case we don't need to build md5 hash for entire query string, because `session` or `utm_source` can be different for all users. The only variables which should be used for md5 hash should be `q` and `page`. Thus, in `config.php` we can use `$config['cache_query_string'] = array('page', 'q');`. So: `$config['cache_query_string'] = FALSE;` → Cache Include Query String is disabled `$config['cache_query_string'] = TRUE;` → Cache Include Query String is enabled for all `$config['cache_query_string'] = array('page', 'q');` → enabled only for specified variables
