When I visit this site http://ifconfig.me/ip using the web browser I
get the expected text output. However if I try to do it from Pharo 6.1
(Windows 8.1) I get a 403 forbidden response using this code:

ZnClient new
�� �� systemPolicy;
�� �� beOneShot;
�� �� accept: ZnMimeType textPlain;
�� �� timeout: 6000;
�� �� url: 'http://ifconfig.me/ip';
�� �� get.

In Firefox this is the output

Any idea?
