错误：子操作不允许执行重定向操作

Question

I used asp.net mvc 5. The action method is:

public ActionResult GetRSSFeed(string  rssfeed, string xslt)
{
    try
    {
        XmlDocument xDoc = new XmlDocument();
        xDoc.Load(rssfeed);
        string returnhtml = ConvertXML(xDoc, Server.MapPath(xslt), new XsltArgumentList());
        //InsertArticlesInDatabase(returnhtml);
        return Content(returnhtml.
            Replace(@"[[ This is a content summary only. Visit my website for full links, other content, and more! ]]",
            ""));
    }
    catch
    {
        return Content("");
    }
}

The code in view is:

Html.Action("GetRSSFeed", "RSSReader", new { rssfeed = Model.RssFeed.ToString(),xslt = Url.Content(Model.XsltTransformation.ToString()), area = "RSSReader" })

When exception is appear the execution does not go in the code in controller.

How can I fix this error, and why that error appear? The code in controller does not redirect anywhere, it just return pure html.

Looks to be a repeat of this: Look here

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