回答: HTTP keepalive是一种应用层的机制,它允许在一个TCP连接上发送多个HTTP请求和响应,而不需要每次都建立新的连接。通过使用keepalive,可以减少连接的建立和关闭的开销,提高网络性能和响应速度。\[1\]在实际应用中,我们可以通过调整keepalive参数来控制等待下一个数据的时长。例如,Gunicorn的keepalive和Nginx的keepalive_timeout参数可以用来设置keepalive的超时时间。\[1\]在设置keepalive参数时,需要注意保持合适的设置,过短的超时时间会导致频繁建立连接,增加服务器的负载,而过长的超时时间则会导致系统中堆积大量无用的HTTP连接,消耗内存资源。因此,具体的设置需要根据网站的浏览量和服务器的配置进行调节。\[2\]如果需要频繁发送请求,可以考虑关闭keepalive,以避免无限建立连接。在Go语言中,可以通过设置http.Client的Transport属性中的DisableKeepAlives为true来关闭keepalive。\[3\]
