Resuming Failed Download Using RSYNC

Situation : 
I have to download some big file from your server. but I don't have access to login in server system.
But using VPN you are able to downlaod some big file.

I tried downloading the big file from the server.
#wget http://10.0.0.1/mypath/mybigfile /root/myfiles/mybigfile
But most of the time the download was not completing, and If I try it using rsync it will ask for password which I was not having, so con't download using rysnc.
So I had to restart it from the beginning (and most probably it fails again, because of some n/w issue)

But now I am able to resume the failed download and continue my task.

Here are the steps
We have other system (say 10.0.0.2) which is local to server and I have credentials for that system.
So first of all I login to 10.0.0.2 and download the bigfile there
#wget http://10.0.0.1/mypath/mybigfile /root/workspace/mybigfile
As the system is local to server, downloading the file there is fast, it takes less than 1 minute.

So afer downloading the file on 10.0.0.2, I resume it using rsync.
rsync --rsync-path=/usr/bin/rsync --partial --progress --rsh=ssh root@10.0.0.2:/root/workspace/mybigfile /root/myfiles/mybigfile
It will ask for the password, supply it, and the downlaod will resume
