Emmanuel Bichet	Thursday 23 June 2011 5:21:08 am Thank for your answer André, but my code was just an example. I've also tried Jquery and the result is the same : - the readystate is 4 (whitch mean the REST api is sending something) - the status of the response is 0 (200 is expected normally) - the responseText is empty (the json format of content/node/2 is expected) I've check the php code in kernel/private/rest. The code make an intensive use of eZ/zeta components MvcTools. The response is created by the MvcResult class. When this class is instanciated, the status properties is set to 0. I think this is the problem. May be there is some change to do in the rest.ini settings...
