annotation:
Because in the previous IIS, the error message on the user application (ASP) could be used by hackers to collect and understand the information on the website settings, database structure, etc., and find security weak links from it and use it to achieve the purpose of intruding the system from the application level. For example, SQL injection attack. In order to strengthen security, these error prompts are blocked by default, and only errors similar to those shown above are displayed. If you need to view error information to solve the code problem during the code opening, debugging, and testing stages, you can just make corresponding modifications in the file accordingly.
