I recorded a series of http packets that I cant programmatically recreate.

The series of packets goes like this:

HTTP     GET /axis-cgi/admin/param.cgi?action=list&group=Network.eth0.MACAddress,Properties.System.SerialNumber,DVTelTest,SightLogix.ProdShortName HTTP/1.1 
HTTP     HTTP/1.1 200 OK  (text/plain)
HTTP     GET /axis-cgi/admin/param.cgi?action=list&group=Properties.Image.Resolution HTTP/1.1 
HTTP     HTTP/1.1 200 OK  (text/plain)
HTTP     GET /axis-cgi/admin/param.cgi?action=update&Network.RTSP.ProtViewer=password HTTP/1.1 
HTTP     GET /axis-cgi/admin/param.cgi?action=list&group=Event HTTP/1.1 
HTTP     HTTP/1.1 200 OK  (text/plain)
HTTP     GET /axis-cgi/admin/param.cgi?action=list&group=ImageSource.I0.Sensor HTTP/1.1 
HTTP     HTTP/1.1 200 OK  (text/plain)

Notice the two GET followed by one response. I though the two gets were going out at the same time but there is no corresponding number of responses. Also when trying to reproduce this pattern as the server if I abort the first GET request the client waits until it times out and starts the request over with out sending any other requests.

What is happening here? How can I reproduce it?
