在没有错误消息的 Page_Error 事件中捕获错误

Question

我每天在我的网站上收到数百封此类错误电子邮件（如果有 500 个服务器错误，我会收到电子邮件）。问题是该消息不是特别有用，我似乎无法重现它或查看它对收到错误的访问者有什么影响。

完整错误消息的一个示例是：

错误消息：Page_Error 事件中捕获错误

在此邮件中未发现病毒。由 AVG 检查 - www.avg.com 版本： 2012.0.1869 / 病毒库：2092/4602 - 发布日期：11/07/11

需要注意的是：

• scirra.com/forum/ 是一个经典的 ASP 应用程序
• 网站的其余部分是 ASP.net

谁能帮我弄清楚这条消息的含义？

就在前几天正在与类似的问题作斗争，罪魁祸首是用户生成的格式错误的 url。
