mod_autoindex, link to the "parent directory" (fwd)
hello,
when displaying http://www.polytechnique.fr/eleves/htdig/apache/ which is
a directory without any index file mod_autoindex produces a list where the
parent directory is referenced as "/htdig/" (the webserver running apache
is www.polytechnique.fr/eleves) and so it doesn't work (should be a href
to "/eleves/htdig/")
it seems to me that any browser can handle an href to "../" (is it true?)
then mod_autoindex could be simplified :
if (is_parent(ar[x]->name)) {
t = ap_make_full_path(scratch, name, "../");
ap_getparents(t);
if (t[0] == '\0') {
t = "/";
}
anchor = ap_pstrcat(scratch, "<A HREF=\"",
ap_escape_html(scratch,
ap_os_escape_path(scratch,
t,
0)),
"\">", NULL);
>> anchor = ap_pstrcat(scratch, "<a href=\"../\">", NULL);
t2 = "Parent Directory</A> ";
}
if I'm wrong, Apache makes the assumption (I posted
several months ago without any response in
comp.infosystems.www.servers.unix) in mod_autoindex, mod_speling
(multiple choices) that an href
to "/" is an href to the web server, not true in all cases
the problem is that ServerName checks for a valid DNS entry and
denies a string like "www.polytechnique.fr/eleves"
any idea?

My guess is that he is doing a proxypass type thing on another server.

in a proxypassed server (see below) the root URL of the web server is not
given by the hostname:port
that's why I ask to replace the href="/" produced by mod_autoindex with a
ref="../"
I ask to put relative links too in the multiple choices (an example
if you want http://www.polytechnique.fr/eleves/joindre_eleve.htm
mod_speling returns a single (sic!) multiple choice to
http://www.polytechnique.fr/joindre_eleve.shtml
because it produces a href="/joindre_eleve.shtml" and not a href to
"joindre_eleve.shtml")
the way to solve it would be to count how many slashes are given in the
URI and to make an href beginning with the string "../" repeated as many
times as necessary instead of using "/", shall I propose a patch ?

yes ... I didn't read it anywhere and Marc's interpretation is the good
one : my server is "proxypassed" by the machine www.polytechnique.fr
however the ProxyPassReverse handles Redirect but does not change web
pages produced by mod_autoindex, mod_speling or others to reflect this
problem; even ServerSignature gives a wrong information (with
UseCanonicalName On or Off)

Sorry, it *is* true. Everything following the hostname, including
any leading slash, is part of the server's private URI space.

For a very good reason - server names follow the same rules as
hostnames, and '/' is not a legal character in a DNS name. If
you've got something like
ServerName www.polytechnique.fr/eleves
in your configuration files, it's broken. From the directive
description:
:ServerName directive
:
:Syntax: ServerName fully-qualified domain name
:Context: server config, virtual host
:Status: core
:
:The ServerName directive sets the hostname of the server; this is
:only used when creating redirection URLs. If it is not specified,
:then the server attempts to deduce it from its own IP address;
:however this may not work reliably, or may not return the preferred
:hostname.
This behaviour isn't a problem, it's how things are supposed to
work.
Out of curiousity, where did you read that '/' was allowed in
DNS names, or that ServerName was allowed to be anything *but*
a valid DNS name? Do we have some bogus documentation somewhere?
