2- Client is connecting a server via TCP to get an object from HTTP Server. Skitch the TCPwindow connection including (establishing connection, the request from client, the response byserver, sending data from server side and closing the connection).Knowing that:1- Get request from the HTTP 1.1 server is 259 bytes.2- Response from the server is 223 bytes.3- Data size requested is 900 bytes.
The following questions are related to HTTP protocol Q1. The first line of a HTTP request from some client to some server is basically made of where the web page file path is added. The path is shown as folders separated by slash. Q2. If an HTTP server responds to a client request and the response is a success, what is the http code and string that marks a success response? Must provide the code and the string as they appear in TCPDump or Wireshark traces. (note: use upper case for the string and also proper spacing in you answers. Keep the order of the string and the code as seen in TCPDump) Answer: code and string that marks a success response Q3. What http header field is used to identify an address of a web page (i.e. the URI) that linked to the resource currently being requested. This field indicates the last page the user/requester was on by the time they link to the requested page. Answer: The field that indicates the last page the user/requester was on is Q4. What is the http…
A browser sends an HTTP request to a web server on port 80. One line of the request is "GET / HTTP/1.1". Explain the purpose of the request,and describe the process that will be used to prepare the response. It is not necessary to show actual content of the HTTP response.
The URL Connection class can be used to read and write data: Select one: a.To the specified resource referred by the HttpResponse and the URL b.To the specified resource referred by the URL c.To the specified resource referred by the HttpServer and the URL d.To the specified resource referred by the ServerSocket and the URL
In this assignment, you will develop a simple Web server in Python that is capable of processing only one request. Specifically, your Web server will (i) Create a connection socket when contacted by a client (browser) (ii) Receive the HTTP request from this connection(iii) Parse the request to determine the specific file being requested(iv) Get the requested file from the server’s file system(v) Create an HTTP response message consisting of the requested file preceded by header lines(vi) Send the response over the TCP connection to the requesting browser. If a browser requests a file that is not present in your server, your server should return a “404 Not Found” error message. Your job is to code the steps above, run your server, and then test your server by sending requests from browsers running on different hosts. If you run your server on a host that already has a Web server running on it, then you should use a different port than port 80 for your Web server. Make sure to test your…

5 Internet Protocol version 4 (IPv4) was deployed on 1 January 1983. The addressformat in IPv4 is a 32-bit numeric value often expressed with four octets from theinterval [0, 255] separated by periods. At the time of writing this book, InternetProtocol version 6 (IPv6), with 128 bit-wide addresses, is slowly replacing IPv4. Intheory, how many IP addresses can be assigned in IPv4 and IPv6?
Q1) How many RTTs are there from when a client first contacts an email server (by initiating a TCP session) to when the client can begin sending the email message itself - that is following all initial TCP or SMTP handshaking required? Recall the figure below from our class notes: "client" SMTP server initiate TCP connection RTT TCP connection initiated SMTP handshaking SMTP transfers "server" SMTP server time 220 HELO 250 Hello
Q: Imagine a Web server that maintains a table in which client IP addresses are mapped to the most recently accessed Web pages. When a client connects to the server, the server looks up the client in its table, and if found, returns the registered page. Is this server stateful or stateless?
Download delays for 100 objects (HTTP 1.1 with browser caching). Consider an HTTP 1.1 client and server. The RTT delay between the client and server is 2 seconds. Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds, as shown below for the first of these 100 requests. initiate TCP connection RTT request file RTT file received time You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 100 requests, one after the other, waiting for a reply to a request before sending the next request. 352 secs Using HTTP 1.1, how much time elapses between the client transmitting the first request, and the receipt of the last requested object, assuming the client uses the IF- MODIFIED-SINCE header line, and 50% of the objects requested have not changed since the client downloaded them (before these 100 downloads are performed)? 350 secs 252 secs time to…
