<h1>Module <a href="type_Authbasic.html">Authbasic</a></h1>

Module <code class="code">Authbasic</code>: Basic HTTP Authentication.<br>
</div>
<hr width="100%">
<br>
This module implements Basic HTTP Authentication as described in
    <a href="http://www.ietf.org/rfc/rfc2617.txt">RFC 2617</a>.  It can be used
    to add an authentication layer to sites with no built-in
    authentication (e.g. static files). Beware, passwords are
    transmitted in cleartext with this scheme, so the medium should be
    secured somehow (by e.g. SSL).
<p>

    This module implements only the HTTP-related part of the protocol,
    and is meant to be extended with various authentication schemes. A
    very naive one (authentication with a single user/password, given
    in the configuration file) is provided.<br>

<pre><span id="VALregister_basic_authentication_method"><span class="keyword">val</span> register_basic_authentication_method</span> : <code class="type">(Simplexmlparser.xml -> string -> string -> bool Lwt.t) -> unit</code></pre><div class="info ">
This function registers an authentication plugin: it adds a new
      parser to the list of available authentication schemes.
<p>

      A parser takes as argument an XML tree (corresponding to the
      first son of an &lt;authbasic&gt; element in the configuration
      file) and returns an authentication function <code class="code">f</code>. <code class="code">f</code> will be
      called for each request with the supplied user and password and
      should return (cooperatively) a boolean telling whether access
      is granted or not. Exceptions are handled the same way as for
      extension parsers.
<p>

      The &lt;authbasic&gt; element must have a <i>realm</i> attribute,
      giving some identifier to the resource which is protected
      (several resources on the same hostname can share the same
      realm). This gives a general customization scheme "for free"
      from the point of view of plugin developers and is totally
      transparent to the plugin.<br>
</div>

<pre><span id="VALget_basic_authentication_method"><span class="keyword">val</span> get_basic_authentication_method</span> : <code class="type">Simplexmlparser.xml -> string -> string -> bool Lwt.t</code></pre><div class="info ">
This function combines all the parsers registered with
      <code class="code">register_basic_authentication_method</code>. It might be useful for
      other extensions. Not for the casual user.<br>
