To answer this question, we need to understand what application pool settings are and which types of applications they apply to.
Application pools in web servers are used to isolate web applications and provide them with separate resources, such as memory and CPU usage. These application pool settings define the environment in which the web application runs.
Now let's go through each option to determine which type of applications do not apply to application pool settings:
Option A) ISAPI - This option is incorrect. ISAPI (Internet Server Application Programming Interface) is a specification that allows developers to extend the functionality of web servers. ISAPI applications can be hosted in application pools and their settings can be configured.
Option B) CGI - This option is correct. CGI (Common Gateway Interface) is a standard protocol for web servers to execute external programs or scripts. CGI applications are executed by the web server as separate processes and do not run within an application pool. Therefore, application pool settings do not apply to CGI applications.
Option C) ASP - This option is incorrect. ASP (Active Server Pages) is a server-side scripting technology for creating dynamic web pages. ASP applications can be hosted in application pools and their settings can be configured.
Option D) ASP.NET - This option is incorrect. ASP.NET is a web application framework developed by Microsoft. ASP.NET applications can be hosted in application pools and their settings can be configured.
The correct answer is B) CGI. CGI applications do not apply to application pool settings.
