Testing sub directories using perl AGAIN

[Shao Zhang <shao@cia.com.au>]

Hi,
    Thank you for all the kind anwsers to my question a couple of weeks
ago.

    But it is still not exactly what I want. All the answers used the
idea to compare the string, but what about
the following case:

dir1 = "/www/info/world";
dir2 = "/www/info/world/usa/../../../."

Now, clearly dir1 is a sub directory of dir2. So how do I test. Since
the security is a big concern of us, we cannot
afford the case like above.


Thanks.

Shao.
