IE运行正常，chrome下却提示：Refused to set unsafe header "Connection"

[luckyboy0212]

前人留下的一个用JSP开发程序，使用 Apache tomcat + MySQL,
发现此程序在IE浏览器运行正常，但用chrome,等浏览器却提示出错，
错误提示是：Refused to set unsafe header "Connection" ，指向this.transport.setRequestHeader(requestHeaders[i], requestHeaders[i + 1]);

以下是部分提示出错的prototype.js的程序代码：
备注： Prototype JavaScript framework, version 1.5.0_rc1

setRequestHeaders: function() {
var requestHeaders =
['X-Requested-With', 'XMLHttpRequest',
'X-Prototype-Version', Prototype.Version,
'Accept', 'text/javascript, text/html, application/xml, text/xml, */*'];

if (this.options.method == 'post') {
requestHeaders.push('Content-type', this.options.contentType);

if (this.transport.overrideMimeType)
requestHeaders.push('Connection', 'close');

}

if (this.options.requestHeaders)
requestHeaders.push.apply(requestHeaders, this.options.requestHeaders);

for (var i = 0; i < requestHeaders.length; i += 2)
this.transport.setRequestHeader(requestHeaders[i], requestHeaders[i + 1]);

},



请大神指教，如何解决此问题，谢谢！

引用 3 楼 antiwise 的回复:

https://stackoverflow.com/questions/7210507/ajax-post-error-refused-to-set-unsafe-header-connection

删除以下这两行代码后： xmlHttp.setRequestHeader("Content-length", params.length); xmlHttp.setRequestHeader("Connection", "close"); 提示：”提交失败，请确认提交数据“ 这个问题怎么解决？因为是新手，期盼大虾们帮忙解决，谢谢！
