Understanding the Requirement:

The question is about the section in the dispatcher.any file that controls permission-sensitive caching behavior.

Dispatcher Configuration:

The dispatcher.any file is the main configuration file for the AEM Dispatcher.

It controls various caching and security-related settings for AEM.

Permission-Sensitive Caching:

Permission-sensitive caching ensures that content is only cached and served to users who have the appropriate permissions.

This setting prevents unauthorized users from accessing restricted content through cached pages.

Relevant Section:

/allowAuthorized:This section controls whether the dispatcher caches content that is restricted by permissions.

When set to "1", it enables permission-sensitive caching, ensuring that only authorized users can access cached content.

Understand the Requirement:

The customer wants to add a field to the properties of all existing and new assets in AEM Assets to capture the asset rating.

The review team needs to fill in the ratings after the assets are uploaded.

Metadata Schemas Tool:

The Metadata Schemas tool in AEM allows you to define metadata schemas that can be applied to assets.

This tool helps in customizing the metadata forms that appear in the properties page of assets.

Create a New Schema:

To add a new property (asset rating), you need to create or update an existing metadata schema.

Navigate to Tools > Assets > Metadata Schemas in AEM.

Select the default schema or create a new schema if necessary.

Add the Rating Property:

Within the selected schema, add a new field for the rating property.

Define the field type (e.g., dropdown, text field) based on how you want the review team to input the ratings.

Configure the field properties, such as label, description, and validation rules.

Apply the Schema:

Apply this metadata schema to the folders where assets are stored. This ensures that all assets within these folders will have the new rating property.

For new assets, the rating property will appear automatically when viewing or editing properties.

Review Team Process:

After the assets are uploaded, the review team can access the properties of each asset and fill in the rating.

The rating property is now part of the asset’s metadata and can be used for sorting, searching, and filtering assets.

Customizing Metadata Schemas in AEM

The cache header that will prevent a file from getting cached in dispatcher isResponse.setHeader("Cache-Control: no-cache").

Cache-Control Header: The Cache-Control header is a directive that specifies caching policies in both requests and responses.

no-cache Directive: Setting the Cache-Control header to no-cache instructs the dispatcher and other intermediaries not to cache the response.

Implementation: By including this header in the response, AEM ensures that the dispatcher retrieves the latest version of the content directly from the AEM instance rather than serving a cached version.
