Asp.Net 范围特定请求 ThreadAbortException 线程被中止
我正在使用 http://pastebin.com/aK0zcxMN 上的课程（ http://dotnetslackers.com/articles/aspnet/Range-Specific-Requests- in-ASP-NET.aspx）以保护下载免遭盗链并提供恢复。它工作正常，但时不时地我得到
System.Threading.ThreadAbortException: Thread was being aborted.

我的网站是一个移动网站，并且有无数不同的移动浏览器，具有不同的下载方法。他们通常还通过运营商网关连接，所以我猜这与客户端断开连接或 wap 代理问题有关。
我想做的是如何阻止这种情况发生。我不想尝试 catc 并忽略它。我已经阅读过相关内容
catch (ThreadAbortException ex)
，
Thread.ResetAbort();
但无法成功地将其应用到课堂上。有没有人使用类似的代码来保护水蛭？
I am using class at http://pastebin.com/aK0zcxMN ( a version of http://dotnetslackers.com/articles/aspnet/Range-Specific-Requests-in-ASP-NET.aspx) to protect downloads from leech and provide resume. It works fine but every now and then i get
System.Threading.ThreadAbortException: Thread was being aborted.

My site is a mobile site and there are gazillions of different mobile browsers around with different approaches to downloads. They also usually connects via operators gateway so I guess it is something to do with client disconnection or wap proxy problem.
What i am trying to do is how can i stop this happening. I don't want to try catc and igonore it. I've read about
catch (ThreadAbortException ex)
and
Thread.ResetAbort();
but could not implement it in to the class successfully. Has anyone used similar code to protect leeching?

如果您使用
Response.Redirect("Some URL");
则尝试此
Response.Redirect("Some URL",false);在这种情况下，响应将不会end 并且您不需要使用 catch 块来处理它。但请确保您的流程不会受到干扰。
if you are using
Response.Redirect("Some URL");then try this
Response.Redirect("Some URL",false);In this case the responce will not end and you dont need to handle it using catch block. But make sure your flow will not disturb.
