web config and machine config

Question

what is the differnce b/w webconfig and machine config

Answer 1

Careful. There is a hierarchy of config files:

applicationHost.config is the top-level IIS config file.

Next is machine.config, which is the top-level, server-specific config file.

Next is a server-level web.config file.

Then there is an application-specific web.config.

Next, there is an optional application.config file.

Finally, there are optional directory-specific web.config files.

The higher-level files often contain directives that limit what you can configure in the lower level files. The highest-level web.config, for example, is where server trust levels are configured.
