Returns the raw payload string from the specified target(s).
If multiple targets are specified, their resulting payloads are
glued together.
Each "target" is a bare URL string or a tuple containing an
address and a dict for what to tack onto the query string.
Finally, a require dict may be passed to enforce a Content-Type
using key 'mime' and/or a minimum payload size using key 'size'.
If using multiple targets, these requirements apply to each
response.
The underlying library here already understands how to search
the environment for proxy settings (e.g. HTTP_PROXY), so we do
not need to do anything extra for that.
If add_padding is True, then some additional null padding will
be added onto the stream returned. This is helpful for some web
services that sometimes return MP3s that `mplayer` clips early.
To prevent redirects one can set allow_redirects to False.
