Network.HTTP.Client.BrReadWithTimeout

Http client with timeouts applied in between body read events.

Note that the response timeout in http-client is applied only when receiving the response headers which is not always satisfactory given that a slow server may send the rest of the response very slowly.

Documentation

fromResponseTimeout :: Request -> Manager -> Int

Converts ResponseTimeout of the request into the number of microseconds.

brReadWithTimeout :: Int -> Request -> BodyReader -> IO ByteString

Reads the next chunk of the response body with the specified timeout.

Note that brRead and httpLbs do not apply any timeouts after reading response headers. This may hang the client if the server implementation is buggy, for instance, when it sends a body of a lesser size than the value of the Content-Length response header. This function solves this problem by applying a timeout passed in the first parameter as a number of microseconds between body read events.

Throws ResponseTimeout if reading of the next chunk of the response body timed out.

httpLbsBrReadWithCustomTimeout :: Int -> Request -> Manager -> IO (Response ByteString)

This is like httpLbs but with a timeout between body read events.

The value of the timeout is passed in the first parameter as a number of microseconds. A negative value effectively disables the timeout which makes the function behave exactly as httpLbs.

httpLbsBrReadWithTimeout :: Request -> Manager -> IO (Response ByteString)

This is like httpLbs but with a timeout between body read events.

The value of the timeout is retrieved from the ResponseTimeout of the request.
