''justdave:'' NO!!! The primary mirrors support it, but there's no way to guarantee that the secondaries do, and the primary mirrors don't have enough available bandwidth to support every Firefox user downloading at once when we have an update. Anything the update service downloads needs to be obtained via our download redirector on download.mozilla.org, so the bandwidth gets distributed to all of the primary and secondary mirrors according to who has bandwidth available. | ''justdave:'' NO!!!

''darin:'' I think you're worrying about something that we can easily solve. Fetching the data via redirect is not a problem for this system. The idea here is that we will try to fetch the files in small chunks. We need to worry about all of the firefox's trying to update themselves, but we can be smart to ensure that they are balanced out. The download redirector could even return an error if the load is too high. Then the firefoxes will wait until some timeout before trying again. Are you sure that the mirrors do not support byte range requests? Even very old versions of Apache supports it for static files. Are you concerned about using HTTP instead of FTP? | |||
