WebSphere and Directory Index

Hello,

we are using WebSphere 4.0.5 with Apache 1.3.29.

In Apaches httpd.conf, I use the config-option
Options -Indexes
which prevent a listing of the files in a directory
on the server.

With a Web Application which has the path eg.
http://server:port/app/jsp/login.jsp

when I point the browser to
http://server:port/app
the browser displays the contents of that
directory. I guess that WebSphere generate
the directory listing. I could not find an
option to turn this behavior off.

Does anyone know how to do or have a hint for the
right google question?

Thanks in Advance.

Regards, Gerhard
