Sorry for not disclosing. I thought I had seen that one on bugtraq. Suppose
there is a document 'http://dummy.com/Public/Index.htm' and 'Index.html' is
'C:\inetsrv\wwwroot\Public\Index.htm'. Then try getting
'http://dummy.com/Public/../../../autoexec.bat' which will give you
'C:\autoexec.bat'. It seems, however, that the first directory ('Public')
will be necessary, i. e. 'http://dummy.com/../../autoexec.bat' won't
work.

But now back to the Unix things.
