Cool.

Yes.

Or like this:
export base="https://curl.haxx.se" # Base url.
export in2="download.html" # New part. Notice that the / is missing.
export in3="#Win64" # Something I added.

curl --append-urls $base $in2 $in3

Or

curl --base-url $base $in2 $in3

Please try something more real world (even contrived). Why would
you want to change hosts? Your example makes no sense to me.

export in1="../download.html"

for i in DragonFlyBSD FreeBSD NetBSD; do
  curl --base-url $base --output-url - $in1 "#" $i | ./download_curl.sh
done

As an award for your work on curl I award you, the extra
large virtual happy face.
