Public methodStatic member GetHtml Displays information about the web server environment.



This class represents a helper, which is a component that simplifies web programming in ASP.NET Web Pages. You can use the ServerInfo class to troubleshoot issues with a website during development and testing. For example, the class can be used to display the virtual and physical paths of the pages in your application, which can help diagnose path-related issues in your code. The ServerInfo class includes many other types of information about the server environment that can be useful in solving programming or site issues, such as the identity of the logged-in user on the current web page, which version of Windows is running on the server, which HTTP method was used to request a web page (GET or POST), and so on.

To display information about the server, call the GetHtml method. The method displays information about the server in a series of HTML tables.
