IIS 6 出于安全考虑, 默认最大请求200K(也即最大提交数据限额为200KByte, 204800Byte).
解决办法:
1. 关闭 IIS Admin Service 服务
2. 打开 \Windows\system32\inesrv\metabase.xml
3. 修改 ASPMaxRequestEntityAllowed 的值为自己需要的, 默认为 204800
4. 启动 IIS Admin Service
Addon: 解决方法2
1. 新建文本文件：
'use VBS
set obj1=GetObject("winmgmts:/root/MicrosoftIISv2")
set obj2=obj1.get("IIsWebVirtualDirSetting='W3SVC/1/ROOT'")
'Output default value
WScript.Echo "AspMaxRequestEntityAllowed Default Value: " & obj2.AspMaxRequestEntityAllowed
'Reset the value
obj2.AspMaxRequestEntityAllowed=1024000 ' set to 1mbyte, u can set to other what you want :)
' Save data
obj2.Put_()
'Output new value
WScript.Echo "AspMaxRequestEntityAllowed New Value: " & obj2.AspMaxRequestEntityAllowed
2. 保存为requestchange.vbs
3. 进入命令行, 运行:
cscript [path]requestchange.vbs
