The error message “A potentially dangerous Request.Path value was detected from the client (<)” indicates that an unhandled exception occurred during the execution of a web request in an ASP.NET application. This security feature prevents potentially harmful input by validating the request path. The underlying issue stems from the client’s input containing characters that are considered unsafe. For developers, reviewing the stack trace is crucial to identify the source of the exception. The exception details point to the error generated by the System.Web.HttpException, specifically triggered by the method ValidateInputIfRequiredByConfig. To resolve this issue, developers should ensure proper input validation and sanitize user inputs to eliminate special characters that may cause security vulnerabilities. This not only enhances application security but also improves user experience by preventing unnecessary errors. Understanding these exceptions is essential for maintaining robust web applications in the .NET framework environment.
