Serving favicon.ico in ASP.NET MVC

Question

I agree with the answer from Chris, but seeing this is a specific ASP.NET MVC question it would be better to use either Razor syntax:

<link rel="icon" href="@Url.Content("~/content/favicon.ico")"/>

Or traditionally

<link rel="icon" href="<%= Url.Content("~/content/favicon.ico") %>"/>

rather than

<link rel="icon" href="http://www.mydomain.com/content/favicon.ico"/>

Placing favicon.ico in the root of your domain only really affects IE5, IIRC. For more modern browsers you should be able to include a link tag to point to another directory:

<link rel="SHORTCUT ICON" href="http://www.mydomain.com/content/favicon.ico"/>

You can also use non-ico files for browsers other than IE, for which I'd maybe use the following conditional statement to serve a PNG to FF,etc, and an ICO to IE:

<link rel="icon" type="image/png" href="http://www.mydomain.com/content/favicon.png" />
<!--[if IE]>
<link rel="shortcut icon" href="http://www.mydomain.com/content/favicon.ico" type="image/vnd.microsoft.icon" />
<![endif]-->

1) You can put your favicon where you want and add this tag to your page head

<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon" />

although some browsers will try to get the favicon from /favicon.ico by default, so you should use the IgnoreRoute.

2) If a browser makes a request for the favicon in another directory it will get a 404 error wich is fine and if you have the link tag in answer 1 in your master page the browser will get the favicon you want.

I think that favicon.ico should be in root folder. It just belongs there.

If you want to servere diferent icons - put it into controler. You can do that. If not - just leave it in the root folder.

None of the above worked for me. I finally solved this problem by renaming favicon.ico to myicon.ico, and reference it in the head <link rel="icon" href="~/myicon.ico" type="image/x-icon" />

It should also be possible to create a controller that returns the ico file and register the route /favicon.ico to point to that controller.
