web.xml配置404,500自定义错误页面无效的解决办法

在IE下总显示IE提供的“友好的错误提示”

可以关闭

IE--工具--Internet选项--高级--取消勾选显示友好 http 错误消息

想显示自己的错误提示，总不能期望客户把这个关上，

IE在响应内容小于一定阀值的情况下会显示友好的错误提示，

解决办法就是充实一下页面,让大小超过512即可

下面列出一张表供大家参考：

代码描述文件大小（阈值）

400	Bad Request	> 512 bytes
403	Forbidden	> 256 bytes
404	Not Found	> 512 bytes
405	Method Not Allowed	> 256 bytes
406	Not Acceptable	> 512 bytes
408	Request Time-out	> 512 bytes
409	Conflict	> 512 bytes
410	Gone	> 256 bytes
500	Internal Server Error	> 512 bytes
501	Not Implemented	> 512 bytes
505	HTTP Version Not Supported	> 512 bytes
