what is a web framework

  1. Although the server is so complicate, it just send plain HTML (CSS,JS) to the client. No magic.

  2. The HTTP protocol is based on a request-response model.

  3. The communication is always initiated by the client. The server has no way of initiating a connection to you and send your browser unsolicited data.

  4. HTTP methods and response codes.

  5. POST requests send to a specific URL, which is specified in the form’s HTML.

  6. Big two problem: routing and templates

    1. How do we map a requested URL to the code that is meant to handle it?
    2. How do we create the requested HTML dynamically, injecting calculated values or information retrieved from a database?
