I can't ACK that anymore; I have wget ten times a file of 22 MByte right
now:

# for i in 1 2 3 4 5 6 7 8 9 10 ; do rm file ; wget http://albatros/share/sisis-dev/guru/file; done
Connecting to albatros (10.0.1.98:80)
file        100%

.... (10x) ....

without any kind of hick-ups;
and the interface does not show any kind of error:
