c# - "Child actions are not allowed to perform redirect actions"

Question

I have this error:

Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

with inner exception:

Child actions are not allowed to perform redirect actions.

Any idea why this happening?

Incidentally, the error is happening on this line:

@Html.Action("Menu", "Navigation")

The Menu Action in the Navigation Controller looks like this:

public ActionResult Menu()
{
    return PartialView();
}

This happened to me because I had [RequireHttps] on the Controller, and a child action was called from a different controller. The RequireHttps attribute caused the redirect
