- In this task, you should: create a CustomHTTPServer class inherited from the HTTPServer class. In the constructor method, the CustomHTTPServer class sets up the server address and port received as a user input. In the constructor, your web server's RequestHandler class has been set up. Every time a client is connected, the server handles the request according to this class. The RequestHandler defines the action to handle the client's GET request. It sends an HTTPheader (code 200) with a success message Hello from server! using the write() method.Descriptionnslookup is a common tool used for querying name servers. A very nice articledescribing its use on Windows machines may be found on a Microsoft Support site. Using nslookup (or if you'd prefer, the commands dig and host will do the job ifthey're installed on your computer), please answer the following questions. For eachquestion, please indicate the command typed into nslookup that you used in orderto answer the question. Look up a web hosting service.o What is the name of the company?o What are its charges per month for storage and bandwidth?o What platform (Windows, Linux, etc)?o Do they do domain name registrations?o If they handle DNS, what are the names and IP addresses of its DNSs?Currently, the client simply sends to the server everything the end-user types. When the server receives these messages it simply echoes them to all clients. Add a mechanism so that the user of the client can type commands that perform special functions. Each command should start with the ’#’ symbol - in fact, anything that starts with that symbol should be considered a command. You should implement the following commands: (a) #quit cause the client to terminate gracefully. Make sure the connection to the server is terminated before exiting the program. (b) #logoff causes the client to disconnect from the server, but not quit. (c) #sethost calls the setHost method in the client. Only allowed if the client is logged off; displays an error message otherwise. (d) #setport calls the setPort method in the client, with the same constraints as #sethost. (e) #login causes the client to connect to the server. Only allowed if the client is not already connected; display an error message…
- In order to access external REST APIs, for this assignment, you must use the requests package to communicate in the HTTP protocol. Finish the implementation of the class called AccessApi. There are 7 method stubs that will need to be completed: A constructor that requires the developer to input a base URL as a string that will host the REST API endpoint. Example: “http://google.com” A method to get the current URL base. A method to set the current URL base. A method to test if the URL is responding to GET requests to allow for a simple alive test. A method to input an endpoint, as a string, and have that endpoint concatenated to the base URL and then send a GET request using the requests package to the combined URL. Then, return the JSON sent as a list. A method to input an endpoint and have that endpoint concatenated to the base URL and then send a GET request using the requests package to the combined URL. Then, return the status code. A method to input an endpoint and have that…You have set up a user group named Accounting and have put all employees in the Accounting department in this group, which has been given permission to use the Financial folder on a file server. You are now asked to create a subfolder under Financial named Payroll. Megan, the payroll officer, is the only employee in the Accounting department allowed to access this folder. What is the best way to configure the new share? a. Assign Megan read/write permissions to the Payroll folder, and explain to your boss that it is not a best practice to give only one employee access to an important folder. b. Assign Megan read/write permissions to the Payroll folder. c. Create a new user group named Payroll, put Megan in the group, and assign the group read/write permissions to the Payroll folder. d. Ask your boss to allow you to put the folder outside of the Financial folder so you can assign a new user group read/write permissions to this folder that will not conflict with the Accounting user group.The Exception shape triggers User Alerts received when only when logged into AtomSphere.

And that you have also created a login system that sets the "username" session variable when a user logs in.Write a simple PHP code that makes use of sessions, mysql insert, update, and delete. The code should first start with a session using session_start(). It should then connect to a MySQL database using mysqli_connect(). It inserts a new record into the users table using mysqli_query() and an SQL INSERT statement. It updates an existing record in the users table using mysqli_query() and an SQL UPDATE statement. It deletes a record from the users table using mysqli_query() and an SQL DELETE statement. It sets a session variable using $_SESSION["username"] and displays it using echo. Finally, it closes the MySQL connection using mysqli_close()
