3. I've tried to download 5 times a big file (wget 
http://192.168.1.213:8081/artifactory/repo/org/hibernate/hibernate-core/4.0.0.CR2/hibernate-core-4.0.0.CR2.jar)
 without problem.
It seems the problem happends when the server is asked to download several 
small files.
>From my client, I did :
$ wget -l 2 -r 
http://192.168.1.213:8081/artifactory/repo/org/jboss/seam/faces/seam-faces/

And after crawling a bit, it stuck on 
"http://192.168.1.213:8081/artifactory/repo/org/jboss/seam/faces/seam-faces/3.1.0-SNAPSHOT/";
 : wget is waiting for something, the little "spaceship" ("<=>") keeps going 
left to right & reverses. Later in my browser, the same page is displayed 
correctly. If I cancel & retry the same command, it sticks somewhere else.
I've tried the same command with --timeout=5 and it sometime times out to 
correctly get it later in another retry.
