7.4 WHAT’S IN A NAME?

EXERCISE 7.4: WHAT’S IN A NAME?

In many circumstances, “read” and “write” are the correct names to use because despite calling one computer a client and one computer a server, they behave as equal peers.

But, if you are dealing with a context where a client only makes requests and the server only responds to requests, you can rename your keys appropriately. The echo client/server we have created is an example of this pattern.

Starting with the code in Listing 7-4 and 7-5, change all references to “read” and “write” data or keys to be “request” and “response” instead. Name them appropriately! The client writes a request and reads a response, while the server reads a request and writes a response. What happens to the relationship between client and server code?
