Sitefinity 3.7, Redirect old HTML pages to CMS page.

In Sitefinity, when editing a page if you click properties you can enter extra page URLs.

Add a new URL something like "~/home.html" and click Save Changes.

Then Make all html pages run as though Asp.Net pages. Look here.

Then add this to the Global.Asax

 void Application_Error(object sender, EventArgs e) 
    {        
//Redirect missing Old html Pages to the default url of that page. Add Additional Urls to pages in sitefinity to redirect to those pages.
        Exception lastException = this.Server.GetLastError();
        if (lastException is HttpException)
        {
            HttpException httpException = (HttpException)lastException;
            if (httpException.GetHttpCode() == 404)
            {
                // get the name of the requested page - just the /thisPage.htm or /DIR/thisPage.asp etc
                string pageName = string.Concat("~", Request.Url.AbsolutePath.ToString());

                // create a new instance of CmsManager
                Telerik.Cms.CmsManager cmsManager = new Telerik.Cms.CmsManager();

                // let's get the page by passing one of it's additional url's
                Telerik.Cms.IPage myPage = cmsManager.GetPageByAdditionalUrl(pageName);

                // we can cast myPage as ICmsPage and redirect to the Default URL
                if (myPage != null)
                {
                    //If there isa default page then redirect to it.                    
                    this.Server.ClearError();                    
                    Response.Redirect(((Telerik.Cms.ICmsPage)myPage).DefaultUrl.Url);
                }
            }
        }
    }
