Technical requirements

Before we start coding our web server, let us list some fundamental characteristics that must be met by our software:

Support for GET and POST methods only
Support for submitting HTML content (pages)
Support for receiving URL parameters (query params) and request body
Support for sending content in plain text (TXT files)
Support for sending images in the following formats:
- JPG/JPEG
- PNG
Handling of successful requests (200 OK response code)
Handling requests where the resource is not found (404 NOT FOUND), as well as generating a standard response page
For any other types of handling errors, generate a 500 INTERNAL SERVER ERROR response code and a standardized page showing the error

In this way, we can generate an understanding of the functioning of requests and HTTP protocol responses.
