@package haxy
@version 0.9


-- | A library for programming custom proxy servers.
module Network.HTTP.Proxy.Server

-- | Proxy entry-point. Spawns a new proxy server.
proxyMain :: HStream s => Settings s -> IO ()

-- | Proxy server settings
data Settings s
Settings :: (Request s -> IO (Request s)) -> (Request s -> Response s -> IO (Response s)) -> Cache s -> (Request s -> IO Bool) -> (String -> IO ()) -> Integer -> Maybe String -> Settings s

-- | A function for modifying requests. Will be called for each request
--   received; the modified request will be forwarded to the target server.
--   Defaults to an identity function.
requestModifier :: Settings s -> Request s -> IO (Request s)

-- | A function for modifying responses. Will be called for each response
--   received; the modified response will be forwarded to the client.
--   Defaults to an identity function.
responseModifier :: Settings s -> Request s -> Response s -> IO (Response s)

-- | The cache. Use <a>def</a> for no cache.
cache :: Settings s -> Cache s

-- | Authorization function. Allows denying certain requests. Defaults to
--   allowing all requests
isAuthorized :: Settings s -> Request s -> IO Bool

-- | A logging function. The default is no logging.
logger :: Settings s -> String -> IO ()

-- | Proxy server port number; default is 3128
portnum :: Settings s -> Integer

-- | The server host name. Defaults to the result of <a>getHostName</a>
hostname :: Settings s -> Maybe String

-- | The cache.
data Cache s
Cache :: (Request s -> IO (Maybe (Response s))) -> (Request s -> Response s -> IO ()) -> Cache s

-- | Retreive the response to a request from the cache.
queryCache :: Cache s -> Request s -> IO (Maybe (Response s))

-- | Record the response to a request in the cache.
recordInCache :: Cache s -> Request s -> Response s -> IO ()

-- | A class for types with a default value.
class Default a
def :: Default a => a
