URLStream with timeout

[Andreas D.]

I use URLSream to receive images from an IP-Camera. If I use it without timeout, the time for URLSream.get() and receive the hole image with URLStream.read() is about 20 mS. If I set a timeout (1000 mS), it takes about 800 mS to receive the imge.
I have the same problem if I use tcpstream and read the http-header by my self.
Have I something misunderstood?
My system: WinXP SP2, VS.NET 2003, commonC++ 1.2.6

What does your code with timeout look like?

[Andreas D.]

I use the demo 'urlfetch".

I add the following code to the class myURLStream:

public:
  myURLStream( timeout_t to=0 ) : URLStream( IPV4, to )
  {
  }

In the main function I changed the first line to:
  myURLStream url( 1000 ); // 1 second timeout

I remove all console output.

I start time measuring before the get command and end after url.close(),
