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)

首先检查 node-httptransfer 的下载 API，以及正在进行的请求、流、临时文件和连接是如何管理的。定义一种与现有 API 兼容的取消机制，然后验证在传输过程中取消或退出时能够释放这些资源，且不会影响已完成的下载。
