问题描述
我有一个与使用IE8浏览器不兼容的应用程序。
I have got an application that is not compatible to work using IE8 browser.
我正在寻找一种方法来配置运行此应用程序的Tomcat，所以这些页面可以被IE8读取并被视为IE7或IE6
I am looking for a way to to configure Tomcat on which this application run, so the pages could be read by IE8 and treated as if they are IE7 or IE6
通过谷歌搜索到目前为止我发现了一个可能的建议，说要添加到http响应标题：
X-UA兼容：IE = EmulateIE7
By googling so far I found a possible suggestion which say to add to the http response the header: X-UA-Compatible: IE=EmulateIE7
here
告诉IE8就像IE7一样。
that tell IE8 to be like IE7.
问题是这种方式需要添加应在应用程序级别添加的过滤器。我想知道你们中是否有人熟悉Tomcat能够将其http内容发送到IE7（或IE6）兼容的更通用的方法吗？
The problem is that this way requires adding a filter that should be added on application level. I'd like to know if any of you is familiar with a more generic way that Tomcat enables to send its http content to be IE7 (or IE6) compatible ?
推荐答案
Tomcat是一个通用的Web服务器和servlet容器。因此，它绝对与浏览器无关，因此无法以某种特殊方式配置它来处理IE。
Tomcat is a general purpose webserver and servlet container. It is absolutely browser-agnostic thus, there's no way to configure it in some special way to deal with IEs.
您不必真正添加过滤器。最低限度是在service方法（或doGet或doPost，无论应用程序使用什么）中的任何位置设置响应头：
You don't have to add filter really. The bare minimum is to set the response header anywhere in "service" method (or doGet or doPost, whatever application uses):
res.addHeader（X-UA-兼容，IE = EmulateIE7）;
res.addHeader("X-UA-Compatible", "IE=EmulateIE7 ");
但是，如果服务器应用程序中有单个入口点，则会出现这种情况。否则过滤器应该以更好的方式完成工作。
But this is in case when there's a single entry point in the server application. Otherwise filter should do the job in a better way.
