Suppose a client sends an HTTP request message with the If-modified-since header. Sup- pose the object in a server has not changed since the last time a client retrieved the object. Then the server will send a response message with the status code: A. 200 OK B. 404 Not Found C. 304 Not Modified D. none of the above
1- A user clicks on the link www.msn.com/index.html. Accordingly, the browser asks the cache server for this page, which is available at the cache from Wed 01 Jun 2017 22:54:43 GMT and it is modified yesterday. Write the HTTP 1.1 conditional GET request/response messages sent/received by the cache server. The answer must include the TCP connection (telnet) command and the necessary headers (if exist).
the nodejs server code is like this const http = require("http");const url = require('url'); var hostName = '127.0.0.1';var port = 3000; var server = http.createServer(function(req,res){res.setHeader('Content-Type','text/plain');const parsed = url.parse(req.url);const pathname = parsed['pathname'] const queryObject = url.parse(req.url,true).query;let queryValue = queryObject['name'] if(queryValue==null){queryValue=""} if (pathname=="/"){res.end("SUCCESS!")}else if (pathname=="/echo"){res.end("SUCCESS! echo")} else if (pathname=="/foxtrot/:name"){queryValue = queryObject['name'].toString()res.end("SUCCESS!
