Async Report Execution not Working

[daniele.pipitone]

Hi,

I'm trying to run a report asynchronously via the restV2 API  

"http://JasperServer]:8080/jasperserver/rest_v2/reportExecutions"

passing (POST) a descriptor like

    /supermart/details/CustomerDetailReport    true    false    false    html    true    false    1-5                        value 1            value 2                            another value            [/code]But Jasper is responding me synchronously , so that when I perform[/code]

HttpWebResponse responseExecution = (HttpWebResponse)requestExecution.GetResponse();[/code]

I get the response only when the execution is completed.
JasperServer 5.5.0 on a windows Machine.

Any suggestions?
Thanks
