(A) Write a server program called GetPostServer that listens on some port. When a client arrives, the server should pass the socket connection to a handler for processing and continue to handle incoming requests.

(B) The Handler should examine the header of HTTP request to see if the message is a GET or POST. If the message is GET, the Handler should attempt to locate the requested file and deliver the content of the file to the client or return an HTML 404 error message that indicates file not found.

(C) If the message type is POST and the header contains a line of the form:
content-type: text/html
read the payload into an array using the content-length: header to determine how many bytes/characters are in the payload (following the blank line).

(D) Decode the form data and send the form data back to the client as:
The form you submitted contains:
=
=
-- each form entry appearing on a different line in the browser (remember, browsers ignore carriage returns so one way to force a new line is to embed the HTML tag
to force a line break).
