50 Allow 10 seconds to receive the request including the headers and
51 30 seconds for receiving the request body:
53 <pre class="prettyprint lang-config">
54 RequestReadTimeout header=10 body=30
60 Allow at least 10 seconds to receive the request body.
61 If the client sends data, increase the timeout by 1 second for every
62 1000 bytes received, with no upper limit for the timeout (except for
63 the limit given indirectly by
64 <code class="directive"><a href="../mod/core.html#limitrequestbody">LimitRequestBody</a></code>):
66 <pre class="prettyprint lang-config">
67 RequestReadTimeout body=10,MinRate=1000
73 Allow at least 10 seconds to receive the request including the headers.
74 If the client sends data, increase the timeout by 1 second for every
75 500 bytes received. But do not allow more than 30 seconds for the
76 request including the headers:
78 <pre class="prettyprint lang-config">
79 RequestReadTimeout header=10-30,MinRate=500
85 Usually, a server should have both header and body timeouts configured.
86 If a common configuration is used for http and https virtual hosts, the
87 timeouts should not be set too low:
89 <pre class="prettyprint lang-config">
90 RequestReadTimeout header=20-40,MinRate=500 body=20,MinRate=500

113 <p>This directive can set various timeouts for receiving the request headers
114 and the request body from the client. If the client fails to send headers or
115 body within the configured time, a <code>408 REQUEST TIME OUT</code> error
118 <p>For SSL virtual hosts, the header timeout values include the time needed
119 to do the initial SSL handshake. If the user's browser is configured to
120 query certificate revocation lists and the CRL server is not reachable, the
121 initial SSL handshake may take a significant time until the browser gives up
122 waiting for the CRL. Therefore the header timeout values should not be set
123 to very low values for SSL virtual hosts.
124 The body timeout values include the time needed for SSL renegotiation
127 <p>When an <code class="directive"><a href="../mod/core.html#acceptfilter">AcceptFilter</a></code> is in use
128 (usually the case on Linux and FreeBSD), the socket is not sent to the
129 server process before at least one byte (or the whole request for
130 <code>httpready</code>) is received. The header timeout configured with
131 <code>RequestReadTimeout</code> is only effective after the server process has
132 received the socket.</p>
134 <p>For each of the two timeout types (header or body), there are three ways
135 to specify the timeout:
140 <li><strong>Fixed timeout value</strong>:<br />
142 <div class="example"><p><code><var>type</var>=<var>timeout</var></code></p></div>
144 <p>The time in seconds allowed for reading all of the request headers or
145 body, respectively. A value of 0 means no limit.</p>
148 <li><strong>Disable module for a vhost:</strong>:<br />
150 <div class="example"><p><code>header=0 body=0</code></p></div>
152 <p>This disables <code class="module"><a href="../mod/mod_reqtimeout.html">mod_reqtimeout</a></code> completely.</p>
155 <li><strong>Timeout value that is increased when data is
156 received</strong>:<br />
157 <div class="example"><p><code>
158 <var>type</var>=<var>timeout</var>,MinRate=<var>data_rate</var>
161 <p>Same as above, but whenever data is received, the timeout value is
162 increased according to the specified minimum data rate (in bytes per
166 <li><strong>Timeout value that is increased when data is received, with an
167 upper bound</strong>:<br />
168 <div class="example"><p><code>
169 <var>type</var>=<var>timeout</var>-<var>maxtimeout</var>,MinRate=<var>data_rate</var>
172 <p>Same as above, but the timeout will not be increased above the second
173 value of the specified timeout range.</p>
