Signalr client methods not called consistently when deployed to IIS -
i stumped on one, have page using collect data on methods being called in web application. when run application visual studio, there no problem, works great, server , client methods function expected.
however, when deploy application webserver running iis 7.5 on windows server 2008, r2 sp1 client side methods not consistently fire, looks running fine. triggering client event never happens.
client side javascript:
var nlog = $.connection.centralhub; $.connection.hub.logging = true; $(function () { var logtable = $("#logtable"); nlog.client.logevent = function (datetime, sitename, clientconid, loglevel, message, stack, emessage) { var tr = $("<tr>"); tr.append($("<td>").text(datetime)); tr.append($("<td>").text(sitename)); tr.append($("<td>").text(clientconid)); tr.append($("<td>").text(loglevel)); tr.append($("<td style='white-space: pre;'>").text(message)); tr.append($("<td>").text(stack)); tr.append($("<td>").text(emessage)); logtable.append(tr); }; nlog.client.test = function() { $("#test").text("spit out test"); } $.connection.hub.start().done(function () { nlog.server.initialmessage(); nlog.server.test(); }, 5000); }); server hub methods:
hub method: centralhub public void initialmessage() { string connid = context.connectionid; _clienttracker.initalmessage(connid); } internal void initalmessage(string connid) { clients.all.logevent( datetime.now.tostring("f"), "harper woods", connid, "info", "hub started", "no message", "no message"); } google console output iis webserver

ok, able find bit of information on going on here. set dependency injection resolver signalr, must done in application_start() method of global.asax, cannot rely on ninject web bootstrapper, , cannot put in owin startup class example on asp.net site. not function predictably work sometimes, miss messages.
