I'm trying to understand my Apache logs, and I keep running across large batches of 206-accesses. That's when someone tries to download a file in small pieces. No biggie. But what I simply don't understand https://community.sophos.com/products/unified-threat-management/f/57/t/50319 is WHY, in downloading a 1 MB file, most people grab it in one piece -- 200 status code, and you're done, and others need MANY HUNDRED separate GETs to get it. Yes, this happens regularly. What is someone doing to make their system need to access my 1 MB file in several hundred byte chunks? Is this something they can fix? I'd appreciate a simple explanation.

On the other hand if your server can't handle that amount of connections you can use mod_bandwidth to limit the connections per IP.

What could be the advantage, in downloading a 1MB file, of doing it in two hundred pieces? Is this where the person downloading has told his system to download two hundred files, and it's splitting the job equally? I'm just trying to envision the situation that is leading to such fractured requests. When downloads are done in this way, it just bloats my log file. Sometimes ridiculously.

If I reboot the phone everything works fine, HTML randomly does and doesn't work (some e-mails load in HTML view and some don't) and then after a few days e-mail stops syncing and the phones PIM Service (Personal information management - BlackBerry Native) starts burning through the battery with heavy CPU utilization. Reboot the phone and everything works fine again for a few days.
