What is Web Server

The term webserver refers to a server that stores web server software and websites files.
To publish a website (static website or dynamic website) we need a web server
Dynamic web sites needs to process data and they generally some kind of business logic
In Static Websites, we have
- Plain HTML
- JavaScript
- CSS
For Dynamic Websites in addition to HTML, JavaScript and CSS we need business logic to be evaluated & For this we need some kind of programming.
When we speak about web servers, some of the popular webservers are
- Apache
- Nginx
- IIS

Simon, Adrian and Jacob Kaplan Moss have refactored the common modules and tools into some thing called THE CMS & Eventually the content management system parts were spun off into a seperate project Ellington CMS
By July 2005, this web development framework was released as Django(prouneced Jang-Oh) after lengendary jazz guitarist Django Reinhart
5000 feet overview of How Django Works
Steps:
- Browser sends the request
- Webserver recieves the requst and hands over the request to WSGI server
- WSGI can run python applications. The request with necessary information (environ) and optionally passes through layers of middleware and ultimately will reach your django application
- URL configuration selects a view to handle the request
- The view might do the following
  - Talk to the database or any external API
  - Renders the HTML
  - Returns the respons
  - Raise an error
- The HttpResponse created will leave the Django application to WebServer and reach browser to render the WebPage
