In this assignment, you will develop a simple socket-based TCP program in C++ for a server that accepts lines of input from a client and prints the lines onto the server’s standard output.  Compile and execute your program. On any other machine that contains a Web browser, set the proxy server in the browser to the host that is running your server program; also configure the port number appropriately. Your browser should now send its GET request messages to your server, and your server should display the messages on its standard output. Use this platform to determine whether your browser generates conditional GET messages for objects that are locally cached

Question

In this assignment, you will develop a simple socket-based TCP program in C++ for a server that accepts lines of input from a client and prints the lines onto
the server’s standard output.  Compile and execute your program. On any other machine
that contains a Web browser, set the proxy server in the browser to the host that is
running your server program; also configure the port number appropriately.
Your browser should now send its GET request messages to your server, and your
server should display the messages on its standard output.
Use this platform to determine whether your browser generates conditional GET
messages for objects that are locally cached

This diagram illustrates the process flow of socket communication between a server and a client. Below is a detailed explanation of each component and their sequence:

**Server Side**

1. **Socket**: The server begins by creating a socket, which is an endpoint for sending and receiving data.

2. **setsockopt**: This step involves configuring the socket options, such as setting timeouts or specifying conditions for socket reuse.

3. **Bind**: The server socket is bound to a specific port and IP address, establishing a location to listen for incoming connections.

4. **Listen**: The server sets the socket to listen mode, allowing it to accept incoming connection requests.

5. **Accept**: The server socket waits for a client connection. Once a client requests a connection, the server accepts it, allowing further communication.

6. **Send/Receive (Send/Recv)**: The server can now send data to and receive data from the client over the established connection.

**Client Side**

1. **Socket**: The client creates its socket, establishing an endpoint for data transmission.

2. **Connect**: The client attempts to connect to the server using the server’s IP address and port number.

3. **Send/Receive (Send/Recv)**: Once the connection is successfully established, the client can send data to and receive data from the server.

The arrows between "Listen" on the server side and "Connect" on the client side indicate the initiation of a connection. Similarly, the bidirectional arrows between "Send/Recv" boxes demonstrate the two-way data transmission capability once the connection is established.
