getting a response to a http request using CVI

Hi,
I am currently trying to acquire some data from an oscilloscope (tektronix TDS3032B) using a TCP connection and CVI/Labwindows 8.1.
After establishing the connection using ConnectToTCPServeur(), I am sending the request to the oscilloscope
using a HTTP 1.1 request (GET) in the function ClientTCPWrite().
The problem is that the lonely responce I get is "HTTP/1.1 100 Continue" and not the data.
I have understand that the server is waiting for a confirmation to send the data but I don't how to confirm.
I am sure that the connection is established because when i am sending a command, it is exectuted by the oscolloscope.
TCP/IP is not the easiest way to communicate with my instrument but it is the only mean i have.

Thanks for your help.
