Which file should a Citrix Administrator edit to configure log settings on the StoreFront server?

The `web.config` file is the primary configuration file for ASP.NET applications, which Citrix StoreFront is built upon, and it contains settings for various aspects including logging levels and providers.

The `global.aspx` file handles application-level events but is not the central configuration file for defining log settings for a web application.

The `logout.aspx` file is specific to the user logout process and does not contain server-wide log configuration settings for StoreFront.

The `default.html` file is typically a static web page and does not contain server-side configuration, including logging settings, for the StoreFront application.
