Answer 1

sure, the piece of code is here..

public static void MetaRedirect(Page p, string url) { HtmlMeta meta = new HtmlMeta();

        meta.Content = "2;url=" + url;
        meta.HttpEquiv = "refresh";

        p.Header.Controls.Add(meta);
    }

Two things spring to mind. The first is potentially overkill but could be useful for other things as well: add a new content area in the master page in the header that you can then use to add any header elements you want. Alternatively you can probably just add a placeholder into your header for much the same effect.
