Sorry Ali, I don't think that's appropriate to the HAProxy mailing list. Other people may help you with this, but it's too close to my usual job for me to spend time on, on the wrong list. Contact me professionally off-list if you like. > From Lukas comments, I realized that at least some parts of the problem are > related to the client agent, is that right?

That probably won't happen. You'll need explicit support on both client and server for HTTP Range requests, which I'm not sure you'll get if you're just exposing download links and expecting a user to re-click after a failed download.
