--- Any network code on Windows requires some initialization, and the network
--- library provides withSocketsDo to perform it. Therefore, proper usage of
--- this library will always involve calling that function at some point.  The
--- best approach is to simply call them at the beginning of your main function,
--- such as:
---
--- > import Network.HTTP.Conduit
--- > import qualified Data.ByteString.Lazy as L
--- > import Network (withSocketsDo)
--- >
--- > main = withSocketsDo
--- >      $ simpleHttp "http://www.haskell.org/" >>= L.putStr

 -- Cookies are implemented according to RFC 6265.

 -- Note that by default, the functions in this package will throw exceptions
