Yes, but you need a web server set up to serve the files you need to copy.

try something like this. On a terminal, start a simple web server:

cd /etc/

python -m SimpleHTTPServer

then open another terminal and do:

wget http://localhost:8000/passwd 

the passwd file will be downloaded to your current directory. You're in effect copying it from /etc/ to your home directory.

I'm not sure why you want to do this but yes, in principle, as you can see, it is possible.
