Ah, good to know.

Yes, you have to help the user to understand what you are asking and _why_ 
you are asking it.

Seems that way.

Interesting. Indeed. When I try this manually it doesn't work either:
welti@ixmp1:~$

Read error (Connection reset by peer) in headers.
Retrying.

There are no firewall restrictions for this machine apart from the usual

The funny thing though is that it works from my own workstation when I 
download it from a browser.
Strange... Maybe an ECN bit problem on the other end...
I'll look into it some more tomorrow.
