In a folder of my Apache webserver I have a .htaccess file with this content:

"# This folder does not require access over HTTP
# (the following directive denies access by default)
Order allow,deny"

What does it mean? does it allow or deny access?

Neither? It tells you that "First, all Allow directives are evaluated; at least one must match, or the request is rejected. Next, all Deny directives are evaluated.

If any matches, the request is rejected. Last, any requests which do not match an Allow or a Deny directive are denied by default." (http://httpd.apache.org/docs/1.3/mod/mod_access.html)

See also http://www.webreference.com/internet/apache/chap5/2/3.html.

Must I cite more?

I think you must look in what context that line is given, e.g.:

<FilesMatch "\.(html)$">
order allow,deny
deny from all
</FilesMatch>

Would mean:
"order allow,deny": first see if who/what is allowed to see the files of the type html; then see who7what is denied acess to those files.
"deny from all": everyone is denied access to the files of type html.

Yes?

Oh, thanks numbers1to9 but it's more difficult than how I expected.

it's better that I ask the direct question then:

I want to install PhpMyAdmin on an Apache webserver.
The last point of the "Quick Install" documentation at http://phpmyadmin.sourceforge.net/documentation says:
"You should deny access to the ./libraries subfolder in your webserver configuration. For Apache you can use supplied .htaccess file in that folder, for other webservers, you should configure this yourself. Such configuration prevents from possible path exposure and cross side scripting vulnerabilities that might happen to be found in that code."

The question is: what must that .htaccess file in the ./libraries subfolder contain?

I believe that if you put:
<Directory />
  Order Deny,Allow
Deny from all
</Directory>

It should suffice.

If the .htaccess is going to work at all you need to hav
AllowOverride None

My last post wasn't quite finished... Stupid "submit button"...

... If the .htaccess is going to work at all you need to have
AllowOverride All set in your server "configuration file".

Mind you, I have all of this a very long time ago, and I barely remember if this is "correct".

At "http://httpd.apache.org/docs/2.2/mod/core.html#directory" you will find all directory functions available for you. And at "http://httpd.apache.org/docs/2.2/misc/security_tips.html" you will find some security pointers (see top Protect Server Files by Default).

(I am assuming that you have Apache 2.2, and that you are using a virtual host)

For some strange reason I can not get <directory /> to work, if you have the same problem try:

<Limit GET>
order deny,allow
deny from all
</Limit>

or simply just  "deny from all".

I found that my original .htaccess file already denies access from my browser.  :)

Anyway I awarded you for your effort. Thanks!
