HTTP.Download.Accelerator

Description

This indicates an attempt to create multi-threaded download sessions via a download accelerator.
Download accelerators increase their speed by using "HTTP range header" to retrieve multiple chunks of a file simultaneously. The signature detects such parallel downloads.
However, this signature ignores single threaded downloads because they are the same as normal browser downloads.
