6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin <p>This directive can set various timeouts for receiving the request headers
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin and the request body from the client. If the client fails to send headers or
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin body within the configured time, a <code>408 REQUEST TIME OUT</code> error

6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin <p>For SSL virtual hosts, the header timeout values include the time needed
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin to do the initial SSL handshake. If the user's browser is configured to
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin query certificate revocation lists and the CRL server is not reachable, the
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin initial SSL handshake may take a significant time until the browser gives up
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin waiting for the CRL. Therefore the header timeout values should not be set
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin to very low values for SSL virtual hosts.
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin The body timeout values include the time needed for SSL renegotiation
6cb5ba7ba62cc211ade9e6b76f82eaae64a3a5d2minfrin (if necessary).</p>
