javascript - jsp中可以更改referer吗？或者如何更改referer？

Question

1. 我想要做的是为每个链接设置不同的引用:

2.下面的解释是我的尝试:

代码1:

<a class="mymovie"
    mytitle="<s:property value="movieLink"/>"
    title="<s:property value="movieDownloadPath"/>" 
    href="javascript:void(0)">
      <s:property value="movieName"/>
</a>

代码2:

$(".mymovie").click(function(){
    $.ajax({
      type:"get",
      url:$(this).attr("title"),
      beforeSend: function(request) {
                    request.setRequestHeader("Referer", $(this).attr("mytitle"));
                },
   });
   alert($(this).attr("title"))
});

效果

chorm，jquery-2.1.4.min.js:4 Refused to set unsafe header "Referer"，jquery-2.1.4.min.js:4 XMLHttpRequest cannot load “This is a FTP link to download movie（like:ftp:/.....rmvb）” Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

在Firefox中，当我点击一个链接时，没有任何效果。有什么想法吗？

Answer 1

通常，不允许更改 referer header 。 There seems to be a workaround ，不过:

delete window.document.referrer;
window.document.__defineGetter__('referrer', function () {
    return "yoururl.com";
});
