Using ajaxSetup beforeSend for Basic Auth is breaking SignalR connection
问题 I have a WebApi secured with Basic Auth which is applied to the entire Api using a AuthorizationFilterAttribute. I also have SignalR Hubs sitting on several of my Api Controllers. Alongside this I have a web page which makes use of my WebApi. The web page is mostly written in Backbone, so in order to make calls to my secured WebApi, I have added the following jquery $.ajaxSetup({ beforeSend: function (jqXHR, settings) { jqXHR.setRequestHeader('Authorization', 'Basic ' + Token); return true; }
