ok, so ? ... I don't see the problem ... at least with your example you get exactly the same thing, that is the '/' but DO have access to it without the '/../' trick ... so you are actualy stilling your own hat ... :-) it seems to me that apache will FIRST rewrite the URL from http://host/dir1/dir2/../ to http://host/dir1/ and THEN lookup the result into the disk ... so, if you try http://dtp.kappa.ro/x/../ you will get the http://dtp.kappa.ro/ even if 'x' dir doesn't exists ... it seems to me like a feature: apache first cleans up the URI ... as I said ... I don't see the problem ...

Today I was browsing the Internet when I came across a server that would not let me view the contents of the root dir. However, it did let me view the contents of a dir within it's root dir.

I submit the following example. First, go to http://backbone.sourceforge.com now, go to http://backbone.sourceforge.net/mrtg-2.8.12/.. (Don't forget the '..'s) I know the server log's it as viewing the readable dir plus the /.. and that files within the root dir, once exposed via the '..', may have a problem with being downloaded. That is easily circumvented via adding in the file name after ..
