OnConnected periodically not authorized

[Leogiciel]

Problem seen in a MVC5 application : client browser has owin token in headers, but periodically doesn't pass it in start request.

Problem appears on any browser, on our test server (VM, Srv2012, IIS8.5).
I has never appeared on my local IIS (7.5 on Win7) with exactly the same code.

CORS enabled didn't change the comportment, neither "longpolling, transport" fix did.

Seems periodical : all start requests are authentified (or unauthentified) by period.
