Exactly what Vlad is saying. The correct solution is:
[url_encode(FromS), url_encode(ToS), url_encode(BodyS), Status,
and FYI, in most cases you don't have to flatten the resulting list
from io_lib:format. If you are writing the data to a port or a file,
the driver will take care of that in a more efficient way.
