uN`/&_$c 8qyEHUN2q 不要使用Response.Redirect,而应该使用Server.Transfer

~7 i{~<? protected void Application_Error(Object sender, EventArgs e) {
JIyS e:p3 if (Server.GetLastError() is HttpUnhandledException)
^ }7O|Y7 Server.Transfer("MyErrorPage.aspx");
A8m06 1 $&@wG //其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
L_Ok?9$ }
4'O,xC ?9~^QRLT 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
