google 网页快照不能访问，非常不方便，总想搞清楚原理。因该是过滤什么的。。。。。
无意中发现用google搜索“search?q=cache”就会出现该死的“该页无法显示”。莫非是过滤“search?q=cache"?
用关键词”search q=cache“搜索，可以。有戏。
在百度（baidu.com)中搜索”search?q=cache“，却又是好的。
猜想过滤的原理是：
所有google ip 地址相关（原来偶尔有几个ip地址可以访问快照的），过滤”search?q=cache“，一发现就搞一下手脚，让你不能访问（而且让你的浏览器一段时间内不能访问google，真是可怕，莫非记录了你的ip？）。
突发奇想：把”search?q=cache“拆开，岂不是可以突破过滤？（原来想把search?q=cache用编码代替，没有成功）。
ok，拷贝快照的地址http://216.239.33.100/search?q=cache:TlXgYjL2YLoJ:www.freemed.org/+freemed&hl=zh-CN&ie=UTF-8
改成http://216.239.33.100/search?hello=world&q=cache:TlXgYjL2YLoJ:www.freemed.org/+freemed&hl=zh-CN&ie=UTF-8
^_^，搞定了。
又发现了一个访问google cache的方法：
http://216.239.33.100/search?q=cache:KR_pUC29AmoJ:www.perl.com/+perl&hl=zh-CN&ie=UTF-8
改成
http://216.239.33.100/linux?q=cache:KR_pUC29AmoJ:www.perl.com/+perl&hl=zh-CN&ie=UTF-8
或者
http://216.239.33.100/bsd?q=cache:KR_pUC29AmoJ:www.perl.com/+perl&hl=zh-CN&ie=UTF-8
或者
http://216.239.33.100/linux?q=cache:KR_pUC29AmoJ:www.perl.com/+perl&hl=zh-CN&ie=UTF-8
或者
http://216.239.33.100/microsoft?q=cache:KR_pUC29AmoJ:www.perl.com/+perl&hl=zh-CN&ie=UTF-8
或者
http://216.239.33.100/custom?q=cache:KR_pUC29AmoJ:www.perl.com/+perl&hl=zh-CN&ie=UTF-8
又发现了可以访问google快照的方法
