发现页面未找到错误....但页面已上传...

e ticket.aspx和网站http://www.volvobusesindia.com

Answer 1

检查页面使用的控件，部分错误是：

（或其中一个依赖项）

这意味着如果您使用MyControl.ascx并且此类文件不存在，则会出现相同的404错误。

Answer 2

检查页面

 eticket.aspx

存在于应用程序的根文件夹中。在线快速查看显示，www.volvobusesindia.com的根目录中不存在eticket.aspx。

也许您的应用程序位于子文件夹中？

Answer 3

http://www.volvobusesindia.com/eticket.aspx给了我404页面找不到异常。你能再次检查一下这个页面的存在吗？

Answer 4

几点：

您当前的背景是clixngo.com还是volvobusesindia。如果它的沃尔沃公共汽车印度，那么我们遇到404.
Response.Redirect（〜/ ..）仅适用于当前域。对于其他域，您必须指定整个字符串。

ASP.NET中找不到页面错误
