[erlang-questions] httpc request - stream to file

Hi,

I'm studying Erlang and have a simple question. In my http request function
i'm using stream to save the output to the file. The question is how to
replace the file content instead of adding additional data to it?

fetch_db_ver() ->
httpc:request(get,
{"http://www.domain.com/CURRENTDBVERSION",[]},
[],
[{stream, "CURRENTDBVERSION"}]
).

current_version() ->
file:read_file("CURRENTDBVERSION").


So, instead of

32154810

I'm getting  "3215334632153346321533463215334632154810"

19> db:current_version().
{ok,<<"3215334632153346321533463215334632154810">>}

-- 
Thanks a lot,
Yury.
