IIS Web.config
IIS Web.config is an XML-based configuration file used to manage settings for websites and applications hosted on Microsoft Internet Information Services (IIS). It allows administrators and developers to define server behaviors, security policies, URL rewriting rules, and application-specific configurations without modifying server-wide settings. The file is typically placed in the root directory of a web application and can be inherited or overridden at different levels in the directory hierarchy.
Developers should learn and use IIS Web.config when deploying ASP.NET, ASP.NET Core, or other web applications on Windows servers running IIS, as it provides a centralized way to control application behavior, security, and performance. It is essential for configuring authentication, authorization, custom error pages, compression, caching, and URL routing in production environments. Understanding Web.config is crucial for troubleshooting deployment issues and optimizing web applications for IIS-specific features.
