I agree Rich. It should not make a blind bit of difference to it. I was
asked why because I knew 'a little bit' about apache. Initially I mocked
it up on an Ubuntu server* running:
Server version: Apache/2.2.9 (Ubuntu)
Server built: Jul 10 2009 18:43:23
and it is CNR.
*The only subtle difference is the default on Ubuntu is the default site
is a Virtual host called in by apache2.conf
On this with the directives set;
DocumentRoot /home/www/htdocs/
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /home/www/htdocs/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Allow from all
</Directory>
and a sub directory /htdocs/protected
with .htaccess within reading:
Order deny,allow
Deny from all
Allow from localhost
Allow from 127.0.0.1
http://localhost/protected/index.html
http://127.0.0.1/protected/index.html
Both serve as they should from localhost - and are refused from another
client.
The log for the call shows;
localhost - - [01/Oct/2009:08:15:07 +0100] "GET /protected/index.html
HTTP/1.1" 200 ....
And has clearly got 'localhost' as the name of the connecting client.
Now, on the Apache on Vista HP (xampp) with the directives set up in
httpd.conf (rather than VIRTUAL) and some slight path differences:
DocumentRoot "C:/xampp/experiment/htdocs"
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>
<Directory "C:/xampp/experiment/htdocs">
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order allow,deny
Allow from all
</Directory>
With a sub directory /images containing .htaccess reading:
Order deny,allow
Deny from all
Allow from localhost
Allow from 127.0.0.1
http://127.0.0.1/images/index.html
Serves as expected
http://localhost/images/index.html
Throws a 403 with log entry:
vista-pc - - [01/Oct/2009:08:19:22 +0100] "GET /images/index.html
HTTP/1.1" 403 ....
It has resolved localhost to it's actual hostname of 'vista-pc' *so IP
to NAME is doing something* This is different to the Ubuntu box which
resolves 127.0.0.1 to 'localhost' and I suspect this is the issue. I
suspect this comes down to how Vista resolves IP to Name, hence I
suspect it is OT.
ASIDE

Calling without naming the index page: http://localhost/images/ shows
the index with the restriction not working (this appears to be dictated
by '-' missing from Indexes. The behaviour consistent across platforms)

I'm sure this is some weirdness in where Vista changing 'localhost' for
the actual hostname. Both the hosts and LMhost.sam file have:
127.0.0.1 localhost
but none the less, it seems to resolve it to 'vista-pc' instead, using
something like 'hostname'. It is not named vista-pc anywhere else, it
has no DNS entries or host file entries for 'vista-pc'. The Ubuntu box
is called 'square', but Apache manages to get 'localhost' for it. I'm
not sure how relevant this is.
The final point - from Vista calling: http://127.0.0.1/images/index.html
Also 404's if you have .htaccess looking like this:
Order allow,deny
allow from localhost
But *works* (serves the page) if you have this;
Order allow,deny
allow from localhost
allow from 127.0.0.1
I'm starting to wonder if this could be a bug? But why only on Vista???
What am I missing here?
