Question

I have the following action method:

[HttpGet, Authorize, OutputCache(Duration = 60, VaryByHeader = "Cookie", Location = OutputCacheLocation.Any)]
public ActionResult Index()

But when I make a request, these are the headers issued:

Cache-Control: private, max-age=60, s-maxage=0
Content-Type: text/html; charset=utf-8
Content-Encoding: gzip
Expires: Fri, 22 Jun 2012 09:56:32 GMT
Last-Modified: Fri, 22 Jun 2012 09:55:32 GMT
Vary: Accept-Encoding

Why isn’t it including the Cookie header in the Vary?

I’ve tried many variations of the OutputCache settings but to no avail 🙁

I hate IIS almost as much as I hate ASP.NET.
