SignalR cross domains can't send big message in IE

[MSAG]

When i run my SingalR application on IE it works with small messages but it will not work with large messages. However, the same code works on chromium with both short and long messages.More confusing is that if you run this code from the project in VS using IE it will work but it does not work running it on IE outside of VS. It does work on all other browsers.

$(function () {
ChatServerUrl = "http://localhost:63201/";
var ChatUrl = ChatServerUrl + "signalr";
SignalrConnection = $.hubConnection(ChatUrl, { useDefaultPath: false });
ChatProxy = SignalrConnection.createHubProxy('myHub');
ChatProxy.on('addMessage', function (from, message) {
$('#listMessages').datalist('appendRow', { text: from + ':' + message.length + ':' + message });
});

    $("#btnSendMessage").click(function () {
        //this not work on IE Stand alone and run on all other browsers and On IE when you run the html page from VS project
        ChatProxy.invoke("sendToAll",

What version of IE? What transport? How big is the message that does not work? What is the error? Does this work when sending in the same domain?

[MSAG]

Thanks for your replay
IE 11 on Windows 10 x64 VS 2015
transport: longpolling
the big message and small message in the code

Code running on IE when run code from inside VS
But didn't run when put it in normal html page
but run on others browser
And the code running on IE just with small message

the problem it doesn't throw an error
it just do nothing

thanks again

[MSAG]

this is my project to see the problem
TestSR.zip
thanks a lot

[davidfowl]

It might just be a browser limitation? Is it CORS + long polling or is it jsonp being used?

[MSAG]

no
both CORS + long polling
and about browser limitation the same browser is work (IE11) when run page from inside VS
please test my project
It is just to explain the problem
@moozzyk
@davidfowl

[MSAG]

is this problem because URL limitation and Data use URL to send data????

[MSAG]

an other thing when run page from VS SignalR use foreverFrame
but if run stand alone SignalR use longpolling
i try to user foreverFrame in stand alone page but it make error access is denied

[MSAG]

helloooooooooooooooooo
Plz just tell me is there a selution?

[moozzyk]

Using developer tools in your browser inspect data being sent to and from the server. Turn on tracing on the client and check what is being written. On the server side check if you don't have any exceptions. In case of error the client should raise error even.

[MSAG]

I did that before
at clinte there is two exceptions when i used foreverframe:
1- access is denied
then
2- object expected
but in longpolling no exceptions
and websocket not connected at all

at Server:
there is no errors at all
///-
notice:
I enable logging at clinte
and
enable EnableDetailedErrors at server
and all the in IE 11
and in other browsers everything is ok
no any exceptions
