Answer 1

+1 A:

So, the reason you ran into your first issue was because the link tag had runat="server" This tells asp.net to treat it as a server control, rather then a literal. Because its a server control, your scriptlet tag (<%= %>) isn't really doing anything, since its a server control property it is treating it as literal text.

There are two ways to handle it. First is to ClientScriptManager to register a startup script. This will put your link tag inside the body, which is the way microsoft says you should do it, but aesthetically isn't that nice. The other option is to do something like this in your Page_Load

var link = new HtmlGenericControl("link");
link.Attributes.Add("rel", "shortcut icon");
link.Attributes.Add("src", ResolveUrl("~/Resources/Pictures/Shared/Misc/favicon.ico"));
link.Attributes.Add("type", "image/x-icon");

Header.Controls.Add(link);

This builds out a control programatically, then adds it to the controls collection on the head, which will render as what you want at the end of the head tag. Problem with this is that its a bit more work, and its better to avoid monkeying with control collections at the code behind level if you can get away with it.

I tried the second one already but it didn't change anything. Control renderer rendered it the way it wants eventually. And yeah I just put the link element under the `<body>` tag and it worked.
