Writing your first Django app, part 2---IE的问题吗？费解

 在Writing your first Django app, part 2中

Start the development server

我运行python manage.py runserver 192.168.12.90:8000

在ie中，用我建立的超级管理员develop/develop登陆，总是提示：

Looks like your browser isn't configured to accept cookies. Please enable cookies, reload this page, and try again.

即使我打开了cookie，仍然一样

于是安装firefox进行测试，结果就好了，很神奇

这是什么原因？
