> Key: SLING-4731
> URL: https://issues.apache.org/jira/browse/SLING-4731
> Project: Sling
> Issue Type: Bug
> Components: Extensions
> Affects Versions: Background Servlets 1.0.0
> Reporter: Joerg Hoh
> Priority: Major
>
> When you do an upload of a large file with "sling:bg=true" appended, the BackgroundHttpServletRequest loads the complete inputstream into memory.
> Would it be possible to have something less memory-intensive? Of course a file upload in the background is questionable ...
