Hi Martyn;

I tried a test to this URL and it successfully ran to completion, meaning I 
got the results.  As others have pointed out, I did find a bug in the 
web100srv program last week that may be the cause of this problem.  I 
failed to issue a shutdown() command when the test completes and this 
causes the client to hang instead of printing the final results.  I posted 
a quick fix earlier this week, and I'll release a new version of the NDT 
code soon.
