Chapter 12, Problem 12.36HW
Explanation of Solution
Implementation of a concurrent prethreaded version of the TINY web server:
For code “echoservers.c” and “echoservers.h” file:
Use section 12.2.1 code.
For code “tiny.c” and “tiny.h”:
Use section 11.6 code.
sample.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Home</title>
</head>
<body>
Tiny server Example
</body>
</html>
main.c:
#include <stdio.h>
#include "csapp.h"
#include "echoservers.h"
//Main function
int main(int argc, char **argv)
{
//Declare variable
int listenfd, connfd;
socklen_t clientlen;
struct sockaddr_storage clientaddr;
static pool pool;
/* If the arguments does not contain two arguments, then display the below statement */
if (argc != 2)
{
fprintf(stderr, "usage: %s <port>\n", argv[0]);
fprintf(stderr, "use default port 5000\n");
listenfd = Open_listenfd("5000");
}
//Otherwise call Open_listenfd function
else
{
listenfd = Open_listenfd(argv[1]);
}
//Then call the init_pool function
init_pool(listenfd, &pool);
//Check condition
while (1)
{
/* Wait for listening or connected descriptor(s) to convert ready */
pool.ready_set = pool.read_set;
pool.nready = Select(pool.maxfd+1, &pool...

Write a simple multithreaded web server in C#. Regardless of the page requested, the server
should respond with an HTML page displaying just the words "PTUK Final Exam C#-Socket-
Programming"
Q2.Recently QUIC protocol is suggested.
a. Elaborate on the advantages of QUIC through an example scenario.
b. The standard protocols, like TCP, UDP and HTTP, are implemented in various languages. For example, Java language has ServerSocket() class for TCP server. Does the QUIC protocol is supported in any language? I mean its library is available. If yes, please explain its working. And run a simple QUIC client program, even if this program is available
over the Internet.
c. List the servers supporting QUIC protocol, if they exist.
Computer Science
C programming
Develop a proxy HTTP server that can accept HTTP requests from clients and convert them to HTTPS request to the web server.
The HTTP request can be filtered based on an access control list.
The requests can be generated by any web client, such as the curl command or a web browser.
the proxy converts plain text HTTP requests from a client to HTTPS requests and then returns the responses to the client.
Main objective is to create a proxy HTTP server that converts cleartext HTTP requests from clients to HTTPS requests to servers and vice versa for the responsesresponses.
