Include some page that returns 401

Question

I've some web page deployed at some server say:

http://myhost/some_secured_file.html

when I access this file within a browser it returns 401 asking me to authorize myself.

The problem is that I am trying to include this page inside some JSP page using the c:import tag.

The app server returns :

javax.servlet.jsp.JspException: Problem accessing the absolute URL "http://myhost/some_secured_file.html". java
    .io.IOException: Server returned HTTP response code: 401 for URL: http://myhost/some_secured_file.html

How I can accomplish the include!?
