9.获取错误信息并到指定页面 >.tP7=
"agc*o~!F
不要使用Response.Redirect,而应该使用Server.Transfer &~%(

`u. /2]n
e.g SGZ]_
// in global.asax YTQom!O
protected void Application_Error(Object sender, EventArgs e) { %XpYiW#AK
if (Server.GetLastError() is HttpUnhandledException) @,Re<%\
Server.Transfer("MyErrorPage.aspx"); i8]2y
Up(Jw-.
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) :X?bWxOJ
} ?|&plf|
!<ae~#]3P
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 M~6x&|2
