私のWebアプリケーションでは、SignalRの動作に矛盾があります。ほとんどの場合、Webアプリケーションのいくつかのページを除いて動作しますが、IE 11とChromeでは表示されません。興味深いことに、Telerikコンポーネント（ASP.NET AJAX 2015.3.1104のUI）があるページでは動作しませんが、これが関連しているかどうかはわかりません。ここでブラウザおよび/またはWebページによっては、SignalRクライアント側が常に呼び出されるとは限りません
は私のハブのjsファイルです：
Firefoxで今$(document).ready(function() {
var connection = $.hubConnection();
connection.logging = true;
connection.start();
$.connection.eCDHub.logging = true;
//get hub
var ecdHub = $.connection.eCDHub;
//on starting page => join the ecd hub to receive notifications
$.connection.hub.start().done(function() {
ecdHub.server.joinECDHub(instId);
try{
ecdHub.server.showRequestToAll(null, 0).done(console.log("showRequestToAll"));
}
catch (err) {
console.log("error (" + err+ ")");
}
console.log("Connected to notifications (" + instId + ")");
}).fail(function (reason) {
console.log("SignalR connection failed: " + reason);
});
//on receiving ecd notification
ecdHub.client.showRequest = function (ecd) {
console.log("eCd notification received");
if (typeof displayComingRequest == 'function') {
displayComingRequest(ecd);
}
//$("#ecdAlertModel").show();
}
ecdHub.client.showRequestToAll = function (ecd) {
console.log("notification received for all");
//displayComingRequest(ecd);
//$("#ecdAlertModel").show();
}
ecdHub.client.showMessage = function (msg) {
console.log("Message received: " + msg);
}
});
私は、次の出来事を参照してください。

だから、明らかに私のクライアント側のメソッドshowRequestToAll（）が呼び出されます。

ブラウザ間で何が起こっているの任意のアイデア？他のページでは、IEとChromeで正常に動作します。 FFでどこでも動作するようです。
