通过http头添加图标 [英] Adding favicon through a http header

问题描述

假设我想在动态生成的页面（特别是ADF Faces页面，但这是不相关的）上添加一个favicon。我无法修改我生成的html的标签。
所以我尝试在servlet头中添加一个http头。我希望我的标题与html head元素相同：

 < link rel =快捷方式图标href =http： //foo.com/favicon.ico\"> 
  

我这样添加它：

  httpResponse.addHeader（Link，< http：//foo.com/favicon.ico> ;; rel = \快捷方式图标\）; 
  

在我的浏览器中，我看到了这个标题：

 链接：< http：//foo.com/favicon.ico> ;;不幸的是，这对IE或Chrome没有任何影响。但是，不幸的是，这对IE或Chrome没有任何影响。任何人都试图达到同样的目的？难道我做错了什么？这是否应该工作？
解决方案
答案是：这种方法依赖于提议的标准还未实现（感谢 Salman A 指出了这一点）。 
如果它工作的话，它会很棒。
 
Let's assume that I want to add a favicon on a dynamically generated page (specifically an ADF Faces page, but this is irrelevant). I can't modify a  tag of my resulted html.
So I try to add a http-header in servlet header. I want my header to be identical to html head element:
<link rel="shortcut icon" href="http://foo.com/favicon.ico">
I'm adding it this way:
httpResponse.addHeader("Link", "<http://foo.com/favicon.ico>; rel=\"shortcut icon\"");
And in my browser I see this header in response:
Link: <http://foo.com/favicon.ico>; rel="shortcut icon"
But, unfortunately, this does not have any effect in IE or Chrome. Anyone tried to achieve the same thing? Am I doing something wrong? Is that should work at all?
解决方案
And the answer is: this method relies on proposed standard (a draft) that is not implemented yet (thanks to Salman A for pointing this out).
Though it would be great if it worked.
