Yes, but depending on what you're actually doing you may be able to
cache enough to skip large chunks in subsequent requests.

Well, I'm working on a script that can transfer large files over HTTP.
The point is that I have a HTTP proxy at school, and so I can use HTTP
only. Moreover, they blocked downloading files bigger than 1MB, and
so, I wanted to transfer files in packets of lets say 990KB, so that
they can be downloaded fine through the HTTP proxy. This means i'm
calling repeatly the script for a next chunk, and that's why I wanted
to keep the FTP connection open.
Write it to a temporary file and store that temporary filename in the
session. When the page is called, get the filesize of the temporary file
and use that as the start of the next chunk to download.
