I am working on a Web Application on the Asp .Net 4.0 framework that uses SignalR, having installed it from the Nuget package. When I debug or run the application without debugging locally it works correctly. However, when it is deployed to the production server it is unable to find the signal/hubs file that is being dynamically injected into the httphandlers. Due to it's dynamic nature it has to be created on the fly, so I can't just copy the working file into the project either.
I have tried the following methods of loading the file:
<script src="/signalr/hubs" type="text/javascript"></script>
<script src="signalr/hubs" type="text/javascript"></script>
And in the code behind:
ScriptManager.GetCurrent(Page).Scripts.Add(new ScriptReference("~/signalr/hubs"));
All of these work locally but not on the server. The path that is rendered in the html looks correct, but there is no file there, delivering a 404 error. If it matters, the server has given the application Full Trust and the application is being run as an application under another site in IIS that uses a subdomain.
The problem was solved by setting the following flags in the web.config.
<configuration>
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true">
</modules>
</system.webServer>
</configuration>
For some reason Nuget did not set these values for Elmah or SignalR
