HTTP HEAD Request and System.Web.Mvc.FileResult

I'm using BITS to make requests to a ASP.NET MVC controller method named Source that returns a FileResult. I know the type FilePathResult uses HttpResponse.TransmitFile, but I don't know if HttpResponse.TransmitFile actua开发者_StackOverflow社区lly writes the file to the response stream regardless of the request type.

My question is, does FileResult only include the header information on HEAD requests, or does it transmit the file regardless of the request type? Or, do I have to account for HEAD requests myself?

The result is forced to react on a request by YOUR ACTION CODE. If you do not do anything special on different request types (e.g. [HttpGet]-Attribute, HttpMethodConstraints in the Route, etc...) The file is just written to the response stream.
