bridge_fd is the bridge forward delay time, in seconds, default 15. bridge_hello is the bridge hello time, in seconds, default 2. bridge_maxage is the bridge’s maximum message time, in seconds, default is 20. bridge_stp controls the spanning tree protocol, on or off. Default is off, and is recommended to stay that way.

bae 联通节点之前一直用的是 63开头的ip,长城宽带一直打不开。。有时 hao123 都打不开。。 ,今天打开 blog 一下就开了。。发现联通节点变成了 202.108.23.200 速度还真不错，不知道是不是前几天我在群里反应长城宽带打不开网站就调整了哈。

在非 ie 都 直用 jsonp cookie 是没问题，但是在 ie 下不能生效，还是得靠 p3p 解决 header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');

之前已经介绍过 phpcloud 空间了，也试用过一个站，不过好像被封了，可能是太占资源了哈哈，把 blog 移过过看看会不会被封掉，转移 blog 还是有点麻类的， phpcloud 的 git 权限和apache 权限不致， wordpress 在线更新是比烦的事，改成 777 可以解决，费力呀。。
