<li>
Allow 10 seconds to receive the request including the headers and
30 seconds for receiving the request body:
<div class="example"><p><code>
RequestReadTimeout header=10 body=30
</code></p></div>
</li>
<li>
Allow at least 10 seconds to receive the request body.
If the client sends data, increase the timeout by 1 second for every
1000 bytes received, with no upper limit for the timeout (exept for
the limit given indirectly by
<div class="example"><p><code>
RequestReadTimeout body=10,MinRate=1000
</code></p></div>
</li>
<li>
Allow at least 10 seconds to receive the request including the headers.
If the client sends data, increase the timeout by 1 second for every
500 bytes received. But do not allow more than 30 seconds for the
request including the headers:
<div class="example"><p><code>
RequestReadTimeout header=10-30,MinRate=500
</code></p></div>

<p>This directive can set various timeouts for receiving the request headers
and the request body from the client. If the client fails to send headers or
body within the configured time, a <code>408 REQUEST TIME OUT</code> error
is sent.</p>
<p>For SSL virtual hosts, the header timeout values include the time needed
to do the initial SSL handshake. The body timeout values include the time
needed for SSL renegotiation (if necessary).</p>
<p>When an <code class="directive"><a href="/mod/core.html#acceptfilter">AcceptFilter</a></code> is in use
(usually the case on Linux and FreeBSD), the socket is not sent to the
server process before at least one byte (or the whole request for
<code>httpready</code>) is received. The header timeout configured with
<code>RequestReadTimeout</code> is only effective after the server process has
received the socket.</p>
<p>For each of the two timeout types (header or body), there are three ways
to specify the timeout:
</p>
<ul>
<li><strong>Fixed timeout value</strong>:<br />
<div class="example"><p><code><var>type</var>=<var>timeout</var></code></p></div>
<p>The time in seconds allowed for reading all of the request headers or
body, respectively. A value of 0 means no limit.</p>
</li>
<li><strong>Timeout value that is increased when data is
received</strong>:<br />
<div class="example"><p><code>
<var>type</var>=<var>timeout</var>,MinRate=<var>data_rate</var>
</code></p></div>
<p>Same as above, but whenever data is received, the timeout value is
increased according to the specified minimum data rate (in bytes per
second).</p>
</li>
<li><strong>Timeout value that is increased when data is received, with an
upper bound</strong>:<br />
<div class="example"><p><code>
<var>type</var>=<var>timeout</var>-<var>maxtimeout</var>,MinRate=<var>data_rate</var>
</code></p></div>
<p>Same as above, but the timeout will not be increased above the second
value of the specified timeout range.</p>
</li>
</ul>
