	浏览器用lastEventId属性读取这个值。一旦连接断线，浏览器会发送一个 HTTP 头，里面包含一个特殊的<syntaxhighlight lang="bash" inline>Last-Event-ID</syntaxhighlight>头信息，将这个值发送回来，用来帮助服务器端重建连接。因此，这个头信息可以被视为一种同步机制。		浏览器用lastEventId属性读取这个值。一旦连接断线，浏览器会发送一个 HTTP 头，里面包含一个特殊的<syntaxhighlight lang="bash" inline>Last-Event-ID</syntaxhighlight>头信息，将这个值发送回来，用来帮助服务器端重建连接。因此，这个头信息可以被视为一种同步机制。

			服务器可以用retry字段，指定浏览器重新发起连接的时间间隔。

			<syntaxhighlight lang="bash">
			retry: 10000\n
			</syntaxhighlight>

			两种情况会导致浏览器重新发起连接：一种是时间间隔到期，二是由于网络错误等原因，导致连接出错。

 Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via an HTTP connection, and describes how servers can initiate data transmission towards clients once an initial client connection has been established. They are commonly used to send message updates or continuous data streams to a browser client and designed to enhance native, cross-browser streaming through a JavaScript API called EventSource, through which a client requests a particular URL in order to receive an event stream. The EventSource API is standardized as part of HTML5 by the WHATWG. The media type for SSE is <syntaxhighlight lang="bash" inline>text/event-stream</syntaxhighlight>.
