Set + <em>max-requests</em> to the maximum number of requests you + want Apache to entertain per connection. A limit is imposed to + prevent a client from hogging your server resources. Set this + to <code>0</code> to disable support.</p> + + <h3>KeepAliveTimeout</h3> + <a href="mod/directive-dict.html#Syntax" + rel="Help"><strong>Syntax:</strong></a> KeepAliveTimeout + <em>seconds</em><br /> + <a href="mod/directive-dict.html#Default" + rel="Help"><strong>Default:</strong></a> <code>KeepAliveTimeout + 15</code><br /> + <a href="mod/directive-dict.html#Context" + rel="Help"><strong>Context:</strong></a> server config<br /> + <a href="mod/directive-dict.html#Status" + rel="Help"><strong>Status:</strong></a> Core + + <p>The number of seconds Apache will wait for a subsequent + request before closing the connection. Once a request has been + received, the timeout value specified by the <a + href="mod/core.html#timeout"><code>Timeout</code></a> directive + applies.</p> + + <h2>When Keep-Alive Is Used</h2> + In order for Keep-Alive support to be used, first the browser + must support it. Many current browsers, including Netscape + Navigator 2.0, and Spyglass Mosaic-based browsers (including + Microsoft Internet Explorer) do. Note, however, that some + Windows 95-based browsers misbehave with Keep-Alive-supporting + servers; they may occasionally hang on a connect. This has been + observed with several Windows browsers, and occurs when + connecting to any Keep-Alive server, not just Apache. Netscape + 3.0b5 and later versions are known to work around this problem. + + + <p>However, Keep-Alive support only is active with files where + the length is known beforehand. This means that most CGI + scripts, server-side included files and directory listings will + not use the Keep-Alive protocol. While this should be + completely transparent to the end user, it is something the + web-master may want to keep in mind.</p> + <!--#include virtual="footer.html" --> + </body> +</html> + |
