## Extension: NDH Associated Servers

Official URL: http://hl7.org/fhir/us/ndh/StructureDefinition/base-ext-associatedServers | Version: 2.0.0-current
Standards status: Trial-use | Maturity Level: 4 | Computable Name: AssociatedServers

This extension is designed to store information about servers that may be associated with the current endpoint. It defines a set of servers that could be linked to this endpoint. If a server is associated, the server's type and URL will be included. For example, if your system features two types of endpoints: a standard endpoint and a proxy endpoint associated with the server. For example, the proxy endpoint can be configured to interface with AEGIS software, allowing the software to record transactions and ensure compliance with pertinent standards or regulations. Implementing such a configuration in a production environment would offer the flexibility to switch between standard and proxy modes (associated server) as necessary. Consequently, it is essential to have both standard and proxy endpoints readily available for seamless transitions as required.
