Zt!$"N., T$"~Vu 不要使用Response.Redirect,而应该使用Server.Transfer
F$tzsz,9n Mb2a;s e.g
yZ,pH1 // in global.asax
S8dfe~ |7: protected void Application_Error(Object sender, EventArgs e) {
.8^mA1fmX if (Server.GetLastError() is HttpUnhandledException)

jFdgFKc) g 4=1['wW //其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
[;,E cw^ }
#Mn?Nn 'yX\y
6I 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
