I am using Tomcat websockets and it is working fine in all browsers except in Safari where it is throwing Unexpected response code 426 error.
I went through web inspector and tried to google it to find solution to this issue.

推荐答案

升级时的 426 响应代码适用于 WebSocket 客户端不符合 WebSocket 标准 RFC-6455 的情况.

The 426 response code on upgrade is appropriate for when your websocket client is not conforming to the WebSocket standard RFC-6455.

参见第 4.2.2 节.发送服务器的开始握手.http://tools.ietf.org/html/rfc6455#section-4.2.2

See Section 4.2.2. Sending the Server's Opening Handshake. http://tools.ietf.org/html/rfc6455#section-4.2.2

   /version/
      The |Sec-WebSocket-Version| header field in the client's
      handshake includes the version of the WebSocket Protocol with
      which the client is attempting to communicate.  If this
      version does not match a version understood by the server, the
      server MUST abort the WebSocket handshake described in this
      section and instead send an appropriate HTTP error code (such
      as 426 Upgrade Required) and a |Sec-WebSocket-Version| header
      field indicating the version(s) the server is capable of
      understanding.

发生了什么，Safari 5.x 没有使用最终的 WebSocket 规范，而是一个早期的实验性草案版本，tomcat 没有正确支持.很少有生产服务器可以这样做了.

What is going on, is that Safari 5.x isn't using the final WebSocket spec, but rather an early experimental draft version, something that tomcat does not correctly support. Few production servers do anymore.
