Support for Interruptible Downloads

Hi team,

We’re requesting support for interruptible downloads in the node-httptransfer module.

This enhancement is needed for the AEM Desktop App, which relies on this library for managing large file downloads from AEM. Currently, if a user cancels a download or exits the application mid-transfer, there’s no clean way to interrupt and release resources tied to the in-progress download request. This can result in wasted bandwidth and lingering connections.

Desired Behavior

- Provide a mechanism (e.g., a cancellation token or similar API) to allow downloads to be programmatically interrupted.
- Ensure that aborting a download cleans up any associated streams, temp files, and connections gracefully.
- Ideally, support should be compatible with existing APIs to minimize integration impact.

Use Case
The AEM Desktop App often downloads large binaries, and it’s important for user experience and system efficiency that users can pause, cancel, or exit downloads mid-way without negative side effects.

We’re happy to collaborate on a proposed solution or contribute if needed. Let us know your thoughts!

Thanks,
Harsh Chiki
(on behalf of the AEM Desktop App team)

Beginnen Sie mit der Überprüfung der Download-API von node-httptransfer und der Verwaltung laufender Anfragen, Streams, temporärer Dateien und Verbindungen. Definieren Sie einen mit den bestehenden APIs kompatiblen Abbruchmechanismus und verifizieren Sie anschließend, dass das Abbrechen oder Beenden während einer Übertragung diese Ressourcen freigibt, ohne abgeschlossene Downloads zu beeinträchtigen.
