<p>Modules can determine the file name, or alter the given URI
in this step. For example, <code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code> will
translate the URI's path into the configured virtual host,
<code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> will translate the path to an alias path,
and if the request falls back on the core, the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> is prepended to the request resource.</p>
<p>If all modules <code>DECLINE</code> this phase, an error 500 is
returned to the browser, and a "couldn't translate name" error is logged
If the URI is nothing more than a local (non-proxy) <code>TRACE</code>
request, the core handles the request and returns <code>DONE</code>.
If no module answers this hook with <code>OK</code> or <code>DONE</code>,
the core will run the request filename against the <code class="directive"><a href="../mod/core.html#directory"><Directory></a></code> and <code class="directive"><a href="../mod/core.html#files"><Files></a></code> sections. If the request
'filename' isn't an absolute, legal filename, a note is set for
