I am not always on the chat, if a lot to do, I am way more efficient
batching my answers by email than doing a lot of small answers on IRC.

Yes, just run xdebug and open the dump file. But another way is to put:

in your config file and then:

use \photon\log\Log;

\Log::debug(array('Remote call' => 'http://foo',
                  'return_code' => 200));

in your code. By default it will write a log file in your defined tmp

What will soon change is that the default output for logging will be the
