web.xml文件中配置<mime-mapping>下载文件类型
TOMCAT在默认情况下下载.rar的文件是把文件当作text打开,以至于IE打开RAR文件为乱码,如果遇到这种情况时不必认为是浏览器的问题,大多数浏览器应该不会死皮赖脸地把二进制文件当作文本打开,一般都是服务器给什么浏览器就开什么.解决方法:
打开conf/web.xml,加入下面的代码.
<

重启TOMCAT,清除IE缓存,再打开RAR的文件时就可以正常下载了.
不同的ContentType 会影响客户端所看到的效果.
默认的ContentType为 text/html 也就是网页格式.
代码如:
<%
response.ContentType
=
"
text/html
"
%>
<!--
＃i nclude virtual
=
"
/ContentType.html
"
-->
显示的为网页,而
<%
response.ContentType
=
"
text/plain
"
%>
<!--
＃i nclude virtual
=
"
/sscript/ContentType.html
"
-->
则会显示html原代码.
以下为一些常用的 ContentType
GIF images
<%
response.ContentType
=
"
image/gif
"
%>
<!--
＃i nclude virtual
=
"
/myimage.gif
"
-->

<%
response.ContentType
=
"

%>
<!--
＃i nclude virtual

<%
response.ContentType
=

"
%>
<!--
＃i nclude virtual
