[maurymmarques]

Fitness for CakePHP 2.0 Changed from cakeError() to MissingConnectionException() Added method to search for the latest revision updates without the review Change the query() method to let you use the methods of socket freely Example: $this->Model->curlGet('_all_dbs'); $this->Model->curlPut('document_name'); $this->Model->curlPost('document_name', array('field' => 'value')); $this->Model->curlDelete('document_name'); $this->Model->curlPost('document_name', array('field' => 'value'), false); $this->Model->curlPost('document_name', array('field' => 'value'), true , false);
