If the client fails to send headers or 113 body within the configured time, a <code>408 REQUEST TIME OUT</code> error 114 is sent.</p> 115 116 <p>For SSL virtual hosts, the header timeout values include the time needed 117 to do the initial SSL handshake. If the user's browser is configured to 118 query certificate revocation lists and the CRL server is not reachable, the 119 initial SSL handshake may take a significant time until the browser gives up 120 waiting for the CRL. Therefore the header timeout values should not be set 121 to very low values for SSL virtual hosts. 122 The body timeout values include the time needed for SSL renegotiation 123 (if necessary).</p> 124 125 <p>When an <code class="directive"><a href="../mod/core.html#acceptfilter">AcceptFilter</a></code> is in use 126 (usually the case on Linux and FreeBSD), the socket is not sent to the 127 server process before at least one byte (or the whole request for 128 <code>httpready</code>) is received. The header timeout configured with 129 <code>RequestReadTimeout</code> is only effective after the server process has 130 received the socket.</p> 131 132 <p>For each of the two timeout types (header or body), there are three ways 133 to specify the timeout: 134 </p> 135 136 <ul> 137 138 <li><strong>Fixed timeout value</strong>:<br /> 139 140 <div class="example"><p><code><var>type</var>=<var>timeout</var></code></p></div> 141 142 <p>The time in seconds allowed for reading all of the request headers or 143 body, respectively.
