QMS API issue on slow networks

Hello,

I'm facing a strange issue with the QMS API when requesting data from the QVSServer (GetUserDocuments for example).

Il the network is good enough there is no problem but on a slow network I have strange error messages. You can reproduce ths with QMS API Client (PowerTools) anf Fiddler2. Enable 'Simulate Modem Speeds' in Fiddler2 (Rules->Performance) and send a GetUserDocuments query in QMS API Client.

query (short version with right X-Service-Key)

SOAPAction: "http://ws.qliktech.com/QMS/11/IQMS/GetUserDocuments"

The response received:

HTTP/1.1 400 Bad Request

Content-Length: 0

Server: Microsoft-HTTPAPI/2.0

Date: Wed, 13 Feb 2013 13:47:18 GMT

Il I disable 'Simulate Modem Speeds' it's working.

I ***thnk*** there is a weird timeout issue in the QVSNetRemote.dll but I'm not sure

Anyone facing the same problem ?

Regards,

David
