juQ&v>9W) Wyu$J 不要使用Response.Redirect,而应该使用Server.Transfer
?sQOz[ig; `N$:QWJ e.g
"Y(stRa // in global.asax
N3?hyR<T protected void Application_Error(Object sender, EventArgs e) {
_@I8B if (Server.GetLastError() is HttpUnhandledException)
q$)$?" Server.Transfer("MyErrorPage.aspx");
gL%%2 }$ om%L>zfB //其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
.?7u'%6x?{ }
tL0<xGI5^ V<~.:G$3H 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
