<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 (except for
|
||
the limit given indirectly by
|
||
<code class="directive"><a href="../mod/core.html#limitrequestbody">LimitRequestBody</a></code>):
|
||
|
||
<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>
|
||
</li>
|
||
|
||
<li>
|
||
Usually, a server should have both header and body timeouts configured.
|
||
If a common configuration is used for http and https virtual hosts, the
|
||
timeouts should not be set too low:
|
||
|
||
<div class="example"><p><code>
|
||
RequestReadTimeout header=20-40,MinRate=500 body=20,MinRate=500
|
||
</code></p></div>
|
||
</li>

|
||
<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. If the user's browser is configured to
|
||
query certificate revocation lists and the CRL server is not reachable, the
|
||
initial SSL handshake may take a significant time until the browser gives up
|
||
waiting for the CRL. Therefore the header timeout values should not be set
|
||
to very low values for SSL virtual hosts.
|
||
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>Disable module for a vhost:</strong>:<br />
|
||
|
||
<div class="example"><p><code>header=0 body=0</code></p></div>
|
||
|
||
<p>This disables <code class="module"><a href="../mod/mod_reqtimeout.html">mod_reqtimeout</a></code> completely.</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>
