cakephp - An error "Class 'HttpSocket' Not Found" occured -

i'm trying update cakephp ver.1.3 2.6.

and found error using mylibraryclass.

error is:

"class 'httpsocket' not found"

and code is:

<?php  class myapiclient {      public function __construct() {         $this->socket = new httpsocket();

so added line before class.

<?php app::uses('httpsocket', 'network/http');  class myapiclient {

but error still shown. there did deal case?

as per our discussion in comments have added following code in app/lib

app::uses('httpsocket', 'network/http');

so please place same in required controller before class definition.

If code
