<h3>Summary</h3>
|
||
|
||
<div class="warning">By using this module you are allowing multiple users
|
||
to host content within the same origin. The same origin policy is a key
|
||
principle of Javascript and web security. By hosting web pages in the same
|
||
origin these pages can read and control each other and security issues in
|
||
one page may affect another. This is particularly dangerous in combination
|
||
with web pages involving dynamic content and authentication and when
|
||
your users don't necessarily trust each other.</div>
|
||
|
||
<p>This module allows user-specific directories to be accessed using the
|
||
<code>http://example.com/~user/</code> syntax.</p>

|
||
|
||
<p>The <code class="directive">UserDir</code> directive sets the real
|
||
directory in a user's home directory to use when a request for a
|
||
document for a user is received. <em>Directory-filename</em> is
|
||
one of the following:</p>
|
||
|
||
<ul>
|
||
<li>The name of a directory or a pattern such as those shown
|
||
below.</li>
|
||
|
||
<li>The keyword <code>disabled</code>. This turns off
|
||
<em>all</em> username-to-directory translations except those
|
||
explicitly named with the <code>enabled</code> keyword (see
|
||
below).</li>
|
||
|
||
<li>The keyword <code>disabled</code> followed by a
|
||
space-delimited list of usernames. Usernames that appear in
|
||
such a list will <em>never</em> have directory translation
|
||
performed, even if they appear in an <code>enabled</code>
|
||
clause.</li>
|
||
|
||
<li>The keyword <code>enabled</code> followed by a
|
||
space-delimited list of usernames. These usernames will have
|
||
directory translation performed even if a global disable is
|
||
in effect, but not if they also appear in a
|
||
<code>disabled</code> clause.</li>
|
||
</ul>
|
||
|
||
<p>If neither the <code>enabled</code> nor the
|
||
<code>disabled</code> keywords appear in the
|
||
<code class="directive">Userdir</code> directive, the argument is treated as a
|
||
filename pattern, and is used to turn the name into a directory
|
||
specification. A request for
|
||
<code>http://www.example.com/~bob/one/two.html</code> will be
|
||
translated to:</p>
|
||
|
||
<table>
|
||
<tr><th>UserDir directive used</th>
|
||
<th>Translated path</th></tr>
|
||
<tr><td>UserDir public_html</td>
|
||
<td>~bob/public_html/one/two.html</td></tr>
|
||
<tr><td>UserDir /usr/web</td>
|
||
<td>/usr/web/bob/one/two.html</td></tr>
|
||
<tr><td>UserDir /home/*/www</td>
|
||
<td>/home/bob/www/one/two.html</td></tr>
|
||
</table>
|
||
|
||
<p>The following directives will send redirects to the client:</p>
|
||
|
||
<table>
|
||
<tr><th>UserDir directive used</th>
|
||
<th>Translated path</th></tr>
|
||
<tr><td>UserDir http://www.example.com/users</td>
|
||
<td>http://www.example.com/users/bob/one/two.html</td></tr>
|
||
<tr><td>UserDir http://www.example.com/*/usr</td>
|
||
<td>http://www.example.com/bob/usr/one/two.html</td></tr>
|
||
<tr><td>UserDir http://www.example.com/~*/</td>
|
||
<td>http://www.example.com/~bob/one/two.html</td></tr>
|
||
</table>
|
||
|
||
<div class="note">
|
||
<strong>Be careful when using this directive; for instance,
|
||
<code>"UserDir ./"</code> would map <code>"/~root"</code> to
|
||
<code>"/"</code> - which is probably undesirable. It is strongly
|
||
recommended that your configuration include a "<code>UserDir
|
||
disabled root</code>" declaration. See also the <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> directive and the <a href="../misc/security_tips.html">Security Tips</a> page for
|
||
more information.</strong>
|
||
</div>
|
||
|
||
<p>Additional examples:</p>
|
||
|
||
<p>To allow a few users to have <code>UserDir</code> directories, but
|
||
not anyone else, use the following:</p>
|
||
|
||
<pre class="prettyprint lang-config">UserDir disabled
|
||
UserDir enabled user1 user2 user3</pre>
|
||
|
||
|
||
<p>To allow most users to have <code>UserDir</code> directories, but
|
||
deny this to a few, use the following:</p>
|
||
|
||
<pre class="prettyprint lang-config">UserDir disabled user4 user5 user6</pre>
|
||
|
||
|
||
<p>It is also possible to specify alternative user directories.
|
||
If you use a command like:</p>
|
||
|
||
<pre class="prettyprint lang-config">UserDir "public_html" "/usr/web" "http://www.example.com/"</pre>
|
||
|
||
|
||
<p>With a request for
|
||
<code>http://www.example.com/~bob/one/two.html</code>, will try to
|
||
find the page at <code>~bob/public_html/one/two.html</code> first, then
|
||
<code>/usr/web/bob/one/two.html</code>, and finally it will send a
|
||
redirect to <code>http://www.example.com/bob/one/two.html</code>.</p>
|
||
|
||
<p>If you add a redirect, it must be the last alternative in the list.
|
||
Apache httpd cannot determine if the redirect succeeded or not, so if you have
|
||
the redirect earlier in the list, that will always be the alternative
|
||
that is used.</p>
|
||
|
||
<p>User directory substitution is not active by default in versions
|
||
2.1.4 and later. In earlier versions, <code>UserDir public_html</code>
|
||
was assumed if no <code class="directive">UserDir</code>
|
||
directive was present.</p>
|
||
|
||
<div class="note"><h3>Merging details</h3>
|
||
<p> Lists of specific enabled and disabled users are replaced, not merged,
|
||
from global to virtual host scope</p></div>
