The business classes have been moved to a dedicated library for reuasibility purpose. If you're using Symfony 2.0.*,
you need to update your deps
file:
[widop-http-adapter]
git=http://github.com/widop/http-adapter.git
Autoload the library:
// app/autoload.php
$loader->registerNamespaces(array(
'Widop\\HttpAdapter' => __DIR__.'/../vendor/widop-http-adapter/src',
// ...
);
Run the vendors script:
$ php bin/vendors update
