asp.net - vNext: Form method POST not working with Debian/Kestrel -

I am trying to create simple asp.net vnext application

I have simple client-side HTML code:

   Password: & lt; Input type = "text" name = "password" & gt; & Lt; Br> & Lt; Input type = "submit" value = "submit" & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt;  

And I have simple server-side code to handle post work:

  [HttpPost] [AllowAnonymous] Public IActionResult login (string login, String password) {if valid (login, password)) {var claims = new [] {new claim (type claim .name, login)}; Var identification = new claim identification (claim, cookie attestation default. Authentication type); Context.Response.SignIn (Identity); Redirect Action ("Index", "Home"); } Return Redirect Action ("Login", "Home"); }  

This works fine with Windows / IIS Express, it does not work with Debian / Castell, server method is not logged in.

So, my question is - how is it working with Debian?
