ASPX files use a markup language similar to HTML, but with embedded server-side code blocks denoted by `% %`. These code blocks are processed on the server before the page is sent to the client. ASP.NET provides a rich set of controls and libraries for building dynamic web pages, handling user input, and interacting with databases. Security considerations include input validation and protection against cross-site scripting (XSS) attacks.
