- cnfServerSoftware :: !Ascii
 A banner string to be sent to clients with "Server" response
 header field.
- cnfServerHost :: !(CI Text)
 The host name of the server. This value will be used in
 built-in pages like "404 Not Found".
- cnfServerPort :: !ServiceName
 A port number (or a service name) to listen to HTTP clients.
- cnfServerV4Addr :: !(Maybe HostName)
 Local IPv4 address to listen to both HTTP and HTTPS
 clients. Set this to (Just 0.0.0.0) if you want to accept
 any IPv4 connections. Set this to Nothing to disable IPv4.
- cnfServerV6Addr :: !(Maybe HostName)
 Local IPv6 address to listen to both HTTP and HTTPS
 clients. Set this to (Just ::) if you want to accept any
 IPv6 connections. Set this to Nothing to disable IPv6. Note
 that there is currently no ways to assign separate ports to
 IPv4 and IPv6 server sockets (but I don't think that will be a
 problem.)
- cnfSSLConfig :: !(Maybe SSLConfig)
 Configuration for HTTPS connections. Set this Nothing to
 disable HTTPS.
- cnfMaxPipelineDepth :: !Int
 The maximum number of requests to simultaneously accept in one
 connection. If a client exceeds this limitation, its last
 request won't be processed until a response for its earliest
 pending request is sent back to the client.
- cnfMaxEntityLength :: !Int
 The maximum length of request entity to accept in octets. Note
 that this is nothing but a default value used by
 Network.HTTP.Lucu.Resource.getForm and such when they are
 applied to Nothing, so there is no guarantee that this value
 always constrains all the requests.
- cnfDumpTooLateAbortionToStderr :: !Bool
 Whether to dump too late abortions to the stderr or not. See
 Network.HTTP.Lucu.Abortion.abort.
- cnfExtToMIMEType :: !ExtMap
 A mapping table from file extensions to MIME Types. This value
 is used by Network.HTTP.Lucu.StaticFile.staticFile to guess
 the MIME Type of static files. Note that MIME Types are
 currently guessed only by file name.
Guessing by file magic might be a good idea but that's not
 implemented (yet).
