• Sessions List: Displays all the requests Fiddler has captured, including method (GET, POST), URL, status code, and response size.
• Inspectors: Shows the details of the selected request, including raw headers, body, cookies, and any structured data (like JSON or XML).
• Timeline: Helps analyze how long each request took to process.
