asp.net - SignalR: Sending message back only to AJAX caller from the code behind page (outside of Hub/PersistentConnection)

Question

I'm struggling with this a bit. What I'm trying to achieve is to send message back to the Ajax caller (aspx page) from the server (aspx page's code behind) to update the progress of a time consuming task being done at the server.

I'm trying the following code from the code behind of the aspx page, but that doesn't seem to work!

_context = GlobalHost.ConnectionManager.GetConnectionContext<MessengerEndpoint>();
_context.Connection.Send(((Connection)_context.Connection).Identity, "hey");

Any suggestions will be greatly appreciated.

Edit: Any takers? @dfowler/@N.TaylorMullen?

首先，您可以尝试（仅尝试）：

Context.Connection.Broadcast ( "hey");

如果它可以工作（我认为它会工作（，问题是Identity，所以你需要打开一个连接并将连接 ID 保存在服务器或客户端中以供以后使用。
