9.获取错误信息并到指定页面 [F{P0({%?
J: I@kM
不要使用Response.Redirect,而应该使用Server.Transfer &^Gp

e.g gr# |ZK.`
// in global.asax "{2niBx
protected void Application_Error(Object sender, EventArgs e) { O.8k [Ht
if (Server.GetLastError() is HttpUnhandledException) 1?Tj
Server.Transfer("MyErrorPage.aspx"); 8]bLp
h2i1w^f
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) #)iPvV'
} ,pVe@ d'
$H&:R&Us
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 A!}Ps"Z
