-- | Reverse proxy HTTP requests, either over raw sockets or with WAI
--   
--   Provides a simple means of reverse-proxying HTTP requests. The raw
--   approach uses the same technique as leveraged by keter, whereas the
--   WAI approach performs full request/response parsing via WAI and
--   http-conduit.
@package http-reverse-proxy
@version 0.1.1.2

module Network.HTTP.ReverseProxy

-- | Host/port combination to which we want to proxy.
data ProxyDest
ProxyDest :: !ByteString -> !Int -> ProxyDest
pdHost :: ProxyDest -> !ByteString
pdPort :: ProxyDest -> !Int

-- | Set up a reverse proxy server, which will have a minimal overhead.
--   
--   This function uses raw sockets, parsing as little of the request as
--   possible. The workflow is:
--   
--   <ol>
--   <li>Parse the first request headers.</li>
--   <li>Ask the supplied function to specify how to reverse proxy.</li>
--   <li>Open up a connection to the given host/port.</li>
--   <li>Pass all bytes across the wire unchanged.</li>
--   </ol>
--   
--   If you need more control, such as modifying the request or response,
--   use <a>waiProxyTo</a>.
rawProxyTo :: (MonadBaseControl IO m, MonadIO m) => (RequestHeaders -> m (Either (Application m) ProxyDest)) -> Application m

-- | Creates a WAI <a>Application</a> which will handle reverse proxies.
--   
--   Connections to the proxied server will be provided via http-conduit.
--   As such, all requests and responses will be fully processed in your
--   reverse proxy. This allows you much more control over the data sent
--   over the wire, but also incurs overhead. For a lower-overhead
--   approach, consider <a>rawProxyTo</a>.
--   
--   Most likely, the given application should be run with Warp, though in
--   theory other WAI handlers will work as well.
--   
--   Note: This function will use chunked request bodies for communicating
--   with the proxied server. Not all servers necessarily support chunked
--   request bodies, so please confirm that yours does (Warp, Snap, and
--   Happstack, for example, do).
