Comment (by rjohnson):

 I have (what seems to be) the same or a similar problem. This is using the
 2009.2.0.1 Haskell Platform installer on XP. In my case however, it
 doesn't seem to be related to a proxy server, as I'm not using one.
 Here is cabal's output:

 and here is wget's output:

 Note that wget also has the "X-Cache: MISS", but it doesn't appear to
 affect the download.
