htaccess basic auth allow only one directory

I am using Drupal 6.

I am trying to use htaccess basic auth to block access to my development site. I have sucessfully added the auth so that only our developers can access it.

But now i want allow anyone to access one module (its links starts with anon/).

For ex: lets assume my site is testsite.com

i开发者_C百科 want to block all requests to all the pages expect testsite.com/anon/*

is it possible? if yes how?

Thanks in advance.

EDIT: first reply didn't work. Here's how to do it:

Check the documentation at http://httpd.apache.org/docs/current/mod/core.html#require, which says this:

<Directory /path/to/protected/>
  Require user david
</Directory>
<Directory /path/to/protected/unprotected>
  # All access controls and authentication are disabled
  # in this directory
  Satisfy Any
  Allow from all
</Directory>

This is for Apache 2, btw.

RewriteCond %{REQUEST_URI} !^/anon
RewriteRule ^(.*) error.html [L]

I can't be sure what I understand is the same as what you want to express. I'm a Chinese and my English is not good~_~

Since I stumbled over this and it cost me some time:

The accepted answer is wrong, it is not possible.
(@Thilo, the answerer says so in the comments).

<Directory> directives don't work in .htaccess context, only in server config or virtual host context (docs). @Thilo's config will work if you put it that context (i.e. httpd.conf, vhosts.conf, or wherever you distro has it) — in .htaccess, you'll get a 500 Internal Server Error, just like OP.
