What if the favicon is not named favicon.ico?

Question

Are there any restrictions on naming the favorites icon (favicon) file as anything other than favicon.ico ?

I know for sure that it can be named anything, as long as the favicon tag refers to the correct file name.

For example:

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

The code above works just fine in displaying the icon.

What I want to know is does this violate any W3C/HTML specifications or this is permitted usage?

Answer 1

根据W3C ，首选方法是在html文档中实际指定favicon，而不是依赖于服务器根目录中的favicon.ico。
