I recently tried to use "Internet Download Manager" to download something from my website running on CentOS. I am using all the default apache packages that came with the 4.4 images.
The one thing I noticed is that IDM says that my server does not support resume capability. Then I noticed that it was only using a single request to fetch the objects. Normally, it splits the request up into 4 requests and downloads 4 portions of the object at the same time. This really improves download times.
Since my ISP seems to limit a single upload stream to my server, I think the best way to allow people faster downloads is to allow them to use something like IDM.
I think the problem is that by default Apache is not allowing byte range download requests. Hence, IDM can't resume an aborted download, or request multiple chunks of a download at once.
I did a google search but couldn't find any information on how to configure it to honour byte range requests. I did find some information about it using filters to support byte range, but that was as far as I could get.
does some kind sole out there know how to enable this?
