Re: Apache HTTPD's magical behavior

[Doru Petrescu <pdoru () kappa ro>]

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 ...
