ASP.NET范围特定的请求ThreadAbortException线程被中止

我在上课 http://pastebin.com/aK0zcxMN (版本 http://dotnetslackers.com/articles/aspnet/Range-Specific-Requests-in-ASP-NET.aspx )以保护下载从水蛭和提供简历。它很好用,但偶尔我会

System.Threading.ThreadAbortException: Thread was being aborted.

我的网站是一个移动网站,周围有无数不同的移动浏览器,有不同的下载方法。它们通常也通过运营商网关连接,所以我猜这与客户机断开连接或WAP代理问题有关。

我要做的是如何阻止这种情况的发生。我不想试一下CATC和iGonore。我读过关于

catch (ThreadAbortException ex)

和

Thread.ResetAbort();

但无法成功地将其实现到类中。有人用类似的代码来保护吸血吗?
