Ideas in this flowchart

• Web server request-response mechanism
• A web server responds to requests for online resources
• The browser initiates a request
• The request is received by the server
• The server handles the request
• The server can produce a response in two ways
• The server retrieves a stored file
• The stored file is returned as the response
• The server dynamically generates a response
• Application logic is used
• Information is retrieved from a database
• The application uses the database information
• A dynamic response is generated
• The response is sent back to the browser
• The browser receives the online resource
• This exchange is a basic mechanism behind modern web applications
