Safety of images under the WEB-INF?

2004-06-17 Thread James Sherwood
Hello,
I am doing a project where I dont want people to be able to link
directly to certian images/files unless they are logged in through my
security framework.

The question is, if I put an images directory under the WEB-INF and
serve the images up through a service, how safe are these images? Can they
be retreived without going through my service(which i can check if they have
access or not) and if so, how?

Thank you,
James

Hi,
No, they can't be viewed directly: the servlet container is prohibited
from serving content under WEB-INF directories by the Servlet
Specification.  This is strictly implemented by all servlet container I
know of, and is easy to test in your installation by trying to access
the image under WEB-INF.

However, if you run Tomcat behind Apache, you should ensure that
none of your WEB-INF folders will be served by Apache.
