csdn blog功能最近更新的比较多，自然相应的也暴露出一些问题。在一次访问的时候，我得到了下面的抱错信息。感觉有几个地方应该做一些小小的处理，贴在这里，瑞江不要骂我啊
1 应该捕获connection timeout异常
2 所有系统异常应该跳转到特定的页面，以便隐藏系统信息
上面直接暴露了源程序的位置，操作系统,.net版本信息
3 不知道是否由于sql server是正版，连接数量有限制，我觉得应该自己实现连接池，最好不要有上限，但是有一个自动回收机制，当多余的连接空闲的时候，自动将超过上限的连接关闭。
4 很多时候连接池是不会饱和的，出现这种现象可能是由于某些访问产生了死锁，需要对sqlserver进行进一步的排查
