[sword-devel] HTTP Transport support (was: Remote Module Repository Wiki)

[DM Smith]

InstallSize doesn't give the download size. HEAD does. For compressed modules and image modules these are fairly close. InstallSize is also fairly recent and not all confs have it. So if our software did use it, it'd have too fall back to another way when not there. 


Doing HEAD on all the parts and summing it is a bother and might involve many latencies (eg mage modules) but is singular for a zip and thus no big deal.
