Is it possible to set a ddns hostname to access a name-based virtual host?

[Hongyi Zhao]

Hi all,

Suppose a file named file.pdf stored in the following web location:   

http://some_domain/path/to/file.pdf

Where, the *some_domain* is a name-based virtual host.  In this case,
is it possible to set a ddns hostname, say through
http://www.changeip.net/, without using *some_domain* itself,  to
access this file?
