Using example HTTP headers show the typical HTTP exchange between a Web Client (Browser, CURL, etc.) and a Web Server, where the client issues (i) a GET and (ii) a POST request via a HTML form containing three different HTML form fields (choose three from SUBMIT, TEXT, CHECKBOX, RADIO).
A large law firm, which has many employees, provides a single email address for each employee. Each employee’s email address is @lawfirm.com. However, the firm did not explicitly define the format of the login. Thus, some employees use their first names as their login names, some use their last names, some use their initials, etc. The firm now wishes to make a fixed format, for example: firstname.lastname@lawfirm.com,that can be used for the email addresses of all its employees. How can this be done without rocking the boat too much?

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.

Please do not use a python code already on the internet. The following code must be written in python for this HW assignment. I will provide a skeleten for the code and you must write some lines of code to satisfy the objective of the prorgram. you need to develop a web server that handles one HTTP request on at a time. the web server should acceptand parse the HTTP request, get the requested file from the server’s file system, and create an HTTP responsemessage consisting of the requested file preceded by header lines, and then send the response directly tothe client. If the requested file is not present in the server, the server should send an HTTP “404 NotFound” message back to the client. Dont need the hole code just right the information and code it to the skeleten pictures below.
1. Start up your web browser and go to the http://gaia.cs.umass.edu/wireshark-labs/alice.txt and retrieve an ASCII copy of Alice in Wonderland. Store this file somewhere on your computer2. Next go to http://gaia.cs.umass.edu/wireshark-labs/TCP-wireshark-file1.html. You will find a form to upload the text file.3. Use the browse button in this form to enter the name of the file on your computer containing Alice in Wonderland. Don’t yet press the “Upload alice.txt file” button in the form4. Now start up Wireshark and begin packet capture.5. Returning to your browser press the “Upload alice.txt file” button in the form to upload the file to the gaia.cs.umass.edu server. Once the file has been uploaded, a short congratulations message will be displayed in your browser window.6. Stop the Wireshark packet captureAnswer the following questions:1. What is the IP address and TCP port number used by client computer (source) that is transferring the file to gaia.cs.umass.edu?2. What is the IP…
n this assignment, you will develop a simple Web server in Python that is capableof 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 filepreceded 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 shouldreturn a “404 Not Found” error message.Your job is to code the steps above, run your server, and then test your server bysending requests from browsers running on different hosts. If you run your serveron a host that already has a Web server running on it, then you should use a differentport than port 80 for your Web server. Make sure to test your program…
