Protect access to files on a web server

This shows how to setup basic auth protection for files or directories.

.htaccess

.htaccess for protecting individual files.

AuthName "Restricted Area" 
AuthType Basic 
AuthUserFile .htpasswd 
AuthGroupFile /dev/null 
<Files file_1.foo>
require valid-user
</Files>
<Files file_2.foo>
require valid-user
</Files>

.htaccess for protecting the whole directory.

AuthName "Restricted Area" 
AuthType Basic 
AuthUserFile .htpasswd 
AuthGroupFile /dev/null 
require valid-user

.htpasswd

Create an .htpasswd file for the username "staff":

htpasswd -c .htpasswd user_name

It will look something like this:

staff:H.j5THn495T97

mod_rewrite

friendly magic cookies with pixel bugs

This makes an URL to a "pixel bug" look more friendly. For example,

 http://www.example.com/images/9948/234/1234.gif

will redirect to:

 http://www.example.com/pixel_bug.php?guid=9948&uid=234&imgid=1234
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/images/.*$ [NC]
    RewriteRule ^images/([0-9]*)/([0-9]*)/([0-9]*).gif$ /pixel_bug.php?guid=$1&uid=$2&imgid=$3 [NC,L]

mod_rewrite for MediaWiki friendly URLs

This is a pain in the ass to get right. There are not many pieces, but I had to keep fiddling with them to get it right. Plus, it's easy to get it almost but not quite right.

Assuming you want the root URI to be /wiki (just like Wikipedia). For example:

 http://www.noah.org/wiki/Htaccess

Move wiki root directory

First move your wiki directory from to w/. This is the filesystem path, not the URI. For example:

 mv /var/www/htdocs/wiki /var/www/htdocs/w

Just to be clear, the wiki/ directory should no longer exist in the filesystem. It will not just be a virtual directory handled by MediaWiki scripts.

MediaWiki LocalSettings.php

$wgScriptPath       = "/w";
$wgArticlePath      = "/wiki/$1";

.htaccess (above the MediaWiki directory)

RewriteEngine on

# This rewrites URIs in the form /wiki/Article_Name to /w/index.php/Article_Name.
RewriteCond %{REQUEST_URI} !^/wiki/index.php.*$ [NC]
    RewriteRule ^wiki/?(.*)$ /w/index.php/$1 [L]

# This takes old style links to articles in the form /wiki/index.php/Article_Name and
# redirects them to the new-style format /wiki/Article_Name.
RewriteCond %{REQUEST_URI} ^/wiki/index.php/.*$ [NC]
    RewriteRule ^wiki/index.php/(.*)$ http://www.noah.org/wiki/$1 [R=301,NC,L]
