"resumed sessions"
Is there a capability within Apache that prevents "resumed sessions"?
Or are resumed sessions denied by default?
By "resumed sessions", I mean the ability to return to a web page,
after having been disconnected, and continue where you left off on,
say, a file download or a data entry form.
Thanks

One of the basic features of HTTP/1.1 is byte-range requests. This means
that a client can ask for a particular part of a file. This is the
feature I imagine clients could use to implement resumed sessions. It is
also what Acrobat uses to feed PDF files a page at a time.
Can it be turned off? Not easily. You may be able to turn it off by
forcing apache to use HTTP/1.0, but I'm not sure. Even if you can, it is
not a particularly healthy thing to do to your server.
I suggest you find another way to accomplish whatever restriction you are
trying to implement.
