Functionality You are to create an enhanced chat system. In particular, you will create a chat client and a chat server that are capable of transmitting messages as well as transferring files. In particular, the system will perform as follows: 1. The server will listen for connections from clients. 2. Once a client is connected, it can send messages, at will, to the server. It will also receive from the server all messages sent by the other connected clients. 3. The user will provide messages to the client using standard input. 4. NOTE: The first message sent by the client must be the name of the user, in order for the server to forward the name of the user who has sent a message. Additionally, the user name will be used to identify the user who owns a file that may be requested by another user. 5. Immediately after receiving a message, the server must forward the message and the name of the user who sent the message to all connected clients, except for the client that sent the message. DO NOT SEND THE MESSAGE BACK TO THE ORIGINATING CLIENT! 6. The format of the combined name and message includes a colon, followed by a single space, immediately after the name of the sender; the message follows. Hence, the format can be represented as follows: 7. Once it receives a message, which now includes the name of the sender, the client will write the message to standard output. 8. The client must write each message on its own line of output. 9. In addition to transmitting and receiving messages, the client and server will also transfer files using a binary transfer method, meaning that all of the bytes of a file will be transmitted exactly as is. 10. Because the client must also transfer files, it will monitor file transfer requests. Although the client could use the same socket connection for transferring files, the user of the client that is sending a file might interfere with the transfer process by sending a text message during the transfer. Therefore, you are strongly encouraged to create a separate socket connection for transferring files. 11. In order to initiate a file transfer request, the client must send the name of the file and the name of the user who owns a copy of the file to the server. A user may request a file at any time, and the name of the file and the owning user must be supplied by the requesting user through standard input. 12. When the server receives a file transfer request, it must immediately initiate a file transfer process. The server may set up a relay between the clients involved, i.e., the requesting client and the supplying client, or it may set up a peer-to-peer connection between the requesting client and the supplying client. In either case, all of the bytes in the file must be transmitted as is. If the file cannot be found or read, the client that is supposed to supply the file may simply ignore the request but it may not terminate. Whether requesting or supplying a file, the client must continue to send and receiv.
