WebSocket 客户端发送的消息到服务端被分段了

悬赏园豆：10 [待解决问题]

场景是客户端发送了一段很长的字符串，但是服务端接收的时候被分段了，这里是哪里有对消息长度做控制吗？前面做测试的时候没有关注消息的长度问题，今天去找了条正式的数据格式做测试，发现被分段接收了。
还是我需要对缓存区做设置？有相关的同学知道是哪里的问题吗？

这是客户端代码：

 1 var webSocket = {};
 2         var CreateWebSocket = function () {
 3             webSocket = new WebSocket("ws://ip/WebSocketHandler.ashx?userKey=cj");
 4             webSocket.onopen = WebSokectOnOpen;
 5             webSocket.onmessage = WebSocketOnMessage;
 6             webSocket.onclose = WebSocketOnClose;
 7         };
 8         //建立连接事件
 9         function WebSokectOnOpen() {
10             webSocket.send(" WebSocket Open Success!");
11         };
12 
13         //监听事件
14         function WebSocketOnMessage(event) {
15             //监听来自客户端的数据
16             console.log(event.data);
17             var v = document.getElementById("jl").value;
18             document.getElementById("jl").value = v +'\r\n'+ event.data;
19         };
20         function WebSocketOnClose() {
21             //监听来自客户端的数据
22             console.log('和服务器断开连接');
23         };

这是服务端代码：

 2     {

 4         private string userKey = "";
 5         private static List<System.Net.WebSockets.WebSocket> CONNECT_POOL = new List<System.Net.WebSockets.WebSocket>();//用户连接池
 6         Random rd = new Random();
 7         public void ProcessRequest(HttpContext context)
 8         {
