### 8.2.3 getOutputLocation(preferredProtocols: ArrayOfString) : String

The method returns a URI that a Hosted Application may use to store output that it may provide back to the Hosting System (e.g., in response to a getData() call).

The Hosted Application indicates, in order of preference, the protocols it can use to store data. The Hosted Application shall at least support both the http: and the file: protocols. The Hosting System selects the most appropriate protocol, potentially taking into account system or security considerations as well as the order of preference. The Hosting System uses the selected protocol in setting up the resources and generating the URI returned to the Hosted Application.

### Note

1. There may be limitations when using the http: protocol when compared to the file: protocol. Some functions that might work with a file: protocol such as seek, rewrite, and delete, may not work with the http: protocol. The Hosted Application should assume that it can only write once in sequential order when the returned output location uses the http: protocol.

2. If any authentication information is needed in order to access the data, this authentication information may be included in the URI.

The Hosting System shall keep the URI active while the Hosted Application is in any state other than IDLE or EXIT, or until such time that the Hosted Application returns the URI to the Hosting System (e.g., in an ObjectLocator returned to the Hosting System in response to a getData() call). The disposition of the data that the Hosted Application sends to this URI is the responsibility of the Hosting System after the Hosted Application transitions to the IDLE state or after the Hosted Application returns the URI to the Hosting System (e.g., in an ObjectLocator returned to the Hosting System in response to a getData() call). After the Hosted Application transitions to IDLE state, the Hosting System need not keep the URI active.

The Hosted Application shall only call this method if the Hosted Application is at the INPROGRESS or COMPLETED states.
