This can be very useful for setting up **resources** that you need to use for the whole app, and that are **shared** among requests, and/or that you need to **clean up** afterwards. For example, a database connection pool, or loading a shared machine learning model.

## Use Case

Let's start with an example **use case** and then see how to solve it with this.

	if iamOS.objAPI == nil {
		return errServerNotInitialized
	}

	bootstrapTraceMsg("loading all IAM items")

	listedConfigItems, err := iamOS.listAllIAMConfigItems(ctx)
	if err != nil {
		return fmt.Errorf("unable to list IAM data: %w", err)
	}

	// Loads things in the same order as `LoadIAMCache()`

	bootstrapTraceMsg("loading policy documents")

	policiesList := listedConfigItems[policiesListKey]
