what - Serving favicon.ico in ASP.NET MVC




what is favicon.ico in mvc (5)

What is the final/best recommendation for how to serve favicon.ico in ASP.NET MVC?

I am currently doing the following:

  • Adding an entry to the very beginning of my RegisterRoutes method:

    routes.IgnoreRoute("favicon.ico");
    
  • Placing favicon.ico in the root of my application (which is also going to be the root of my domain).

I have two questions:

  • Is there no way to put the favicon.ico somewhere other than the root of my application. It's pretty icky being right there at the same level as Content and Controllers.
  • Is this IgnoreRoute("favicon.ico") statement sufficient - or should I also do the following as discussed in a blog post from Phil Haack. I'm not aware of ever having seen a request to favicon.ico in any directory other than the root - which would make this unnecessary (but it's good to know how to do it).

    routes.IgnoreRoute("{*favicon}", new {[email protected]"(.*/)?favicon.ico(/.*)?"});
    

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 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"/>

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.


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" />


Use this instead of just the favicon.ico which tends to search in for the fav icon file

> <link rel="ICON" 
> href="@System.IO.Path.Combine(Request.PhysicalApplicationPath,
> "favicon.ico")" />

Use the requested path and combine with the fav icon file so that it gets the accurate address which its search for

Using this solved the Fav.icon error which is raised always on Application_Error
