When one clicks on a link to a PDF in the Web browser, does Adobe Reader
download the whole PDF before it is possible to view it, or does it
download only the pages the user navigates to?
Depends on three things.
First, is the PDF "linearized". Called "Fast Web View Enabled" in
the Acrobat UI, this is a way to restructure a PDF to make it possible to
"byte serve" it. If a PDF is not linearized, it MUST be downloaded in its
entirety before viewing.
Second, the web server support byte serving. This is a feature of
http/1.1 and therefore should be standard on any but the dumbest web servers.
Third, the user must have the "download pages in background"
option enabled in Acrobat (and be using Acrobat and NOT some 3rd party
viewer). This option is enabled by default, but a user may choose to turn
it off.
If all three criteria are met - then the file can/is downloaded on
demand.
