1. IE下载Office2007文件时在下载对话框中变成ZIP文件问题的解决
   
2. 
   
3. 
   
4. 从IIS或者Tomcat之类的Web服务器通过二进制流下载文件时（比如通过设置Header为Content-disposition:inline），如果被下载的文件是Office2007的dotx,docx,pot等后缀的时候，下载对话框中的图标会变成ZIP的，相应的文件名也会成为zip为扩展后缀的文件。其实出现这样的情况，是由于IE中对下载文件类型的判断，假如找不到相应后缀的MIME的话，会自动根据数据流来判断文件的类型，而微软对Office2007的格式做了和以前完全不同的处理。

7. 
   
8. 以前的Office文档是100%的二进制格式。第三方的工具操作起来非常不方便，而 Office2007从整体上都是基于XML格式的，这里并不是说Office2007文档可以保存成XML格式。而是Office2007默认的文档格式就是XML的（Word的docx、Excel的xlsx等）。也许有人会感到奇怪，用文本编辑器打开docx后，显示的仍然是二进制格式，并不是什么 XML。其实docx并不是普通的XML格式，当然，也不只是一个XML文件，docx本质上是一个zip文件，里面有一系列的xml、目录和其他的文件。如果我们将docx改成zip。就可以用winzip等软件将其解开。
   
9. 
   
10. 正是由于这样的原因，当MIME中不存在相对应的Office2007类型的情况下，被自动识别为ZIP文件了。解决的方法很简单，在Server端添加MIME映射就可以了。Tomcat的话，可以在Web.xml中找到<mime-mapping></mime-mapping>这样的定义，按照规则添加就可以了，IIS中按照下面的方法添加（以XML为例）：
    
11. 
    
12. 1.选择Default Web Site，弹出Properties对话框。
    
13. 2.选择HTTP Headers标签。
    
14. 3.在MIME Map下,单击File Types 标签并选择New Type。
    
15. 4.在Extension 域中键入.xml，在 Content Type 域中键入text/xml, 然后单击OK。
    
16. 至于什么是MIME，一般的人应该都知道，这里简单的解释一下：
    
17. MIME (Multipurpose Internet Mail Extensions,多目的Internet邮件扩展)是创建用于电子邮件交换，网络文档，及企业网和Internet上的其他应用程序中的文件格式的规范。每个MIME格式包含一个MIME内容类型（”MIME type”）和指示存储在这个文件中的数据的子类型。MIME类型和子类型一般以类型/子类型的形式列出。MIME格式的内容广泛用于网络文档中
    
18. 
    
19. 下面收集了大部分文件的扩展名和相应的MIME对应，有需要的可以在列表中找到并添加。
