HTTP File Streaming Server

Description​

The Http File Streaming Server is an inbound channel, provides HTTP service interface for the HTTP File Streaming Client. The client can upload files to the server or download files from server. The Transmission ID is used for identifying a set of data that has to be transferred.

The Transmission ID is mapped to a local folder of the server. In case of an upload, all files that the client sends are stored under the Transmission ID within the target folder. In case of a download, the server looks in the outbound folder for a transmission folder. If it exists, all files in this folder can be transferred to the client.

When ever a transmission is completed, an event is sent to orchestra that allows the creation of a process instance that can schedule proper actions like removing the files automatically after download.


Note: The transferred files are not deleted automatically. Please take care that the deletion of unused files is done when a transmission is over.
