(i sent this message to the mail of author, specified at hackage, but it
returned to me, so i decided to resend it here)

I found strange thing during work with latest versions of CouchDB & HTTP
module on my Mac OS X 10.4. The problem is, that when i send document to
the couchdb server, it name was cut to the 2 characters.

After some investigation i found, that this is problem in combination of
the CouchDB + HTTP usage.  CouchDB module fills out the Request structure,
and specify scheme & authority fields.  This lead that i see (in network
dumps) following data:

Content-Type: ...

instead of proper 

PUT /test1/Users_ott_tmp_1_tst HTTP/1.1

I can eliminate this by explicitly setting of the scheme & authority into
empty values, but this lead to improper creation of the  Host header in

PUT /test1/Users_ott_tmp_1_tst HTTP/1.1
Content-Type: ...

I tried to fix this problem myself, but I'm novice in the industrial
Haskell programming ;-)

P.S. this code from (CouchDB/HTTP.hs) will restore proper behaviour of the
code, but break Host header

makeURL path query = CouchMonad $ \conn -> do
  return ( (ccURI conn) { uriPath = '/':path
                        , uriQuery = if null query then "" else '?':(urlEncodeVars query)
                        , uriScheme = ""
                        , uriAuthority = Nothing
         ,conn )
