xsp

XSP (XML Scripting Pages) is a command line tool developed as part of the Mono framework, an open-source implementation of the .NET framework. It allows developers to run server-side web applications using the ASP.NET framework on operating systems that do not natively support it, such as Linux and macOS.

XSP acts as a lightweight web server that listens for HTTP requests and serves pages written in ASP.NET. It supports many features of ASP.NET, including compiled or interpreted code, server-side controls, and session management.

Developers can use XSP to run and test ASP.NET applications locally during development in order to ensure compatibility across different platforms. It's particularly useful for cross-platform development and for those who prefer working with the command line interface.

XSP is highly extensible, allowing developers to plug in additional functionality, add support for different protocols, or customize the server behavior according to their specific requirements.

Apart from the command line interface, XSP can also be used as a library, enabling integration with other applications or frameworks.

Commonly used in conjunction with other tools like Apache or Nginx, XSP can act as a reverse proxy, allowing developers to route requests to their ASP.NET application running on XSP.

XSP supports both the HTTP and HTTPS protocols, providing secure communication options for web applications.

One of the notable features of XSP is its ability to run multiple instances concurrently, which allows handling simultaneous requests and improving application performance.

The tool includes comprehensive logging capabilities, making it easier to track errors and debug ASP.NET applications during development.

XSP has gained popularity in the open-source community due to its efficiency, reliability, and compatibility with various operating systems.
