自定义 HttpHandler 在 IIS 7 中不工作，但在 IIS 5 中工作

我正在我的应用程序中使用自定义 IHttpHandler。它在 IIS 5 中运行良好。但现在我们要迁移到 IIS 7，因此我们购买了 2008 R2 服务器。这里不起作用。请帮助。您可以通过[电子邮件受保护]与我联系。提前致谢。这是我的自定义处理程序代码：

公共类 WebRequestHandler ：IHttpHandler，IRequiresSessionState
{
私有无效 ProcessDataRequest（HttpContext 上下文）
{
控制器控制器=新控制器();
控制器.ProcessDataRequest(上下文);
}

区域 IHttpHandler 成员

公共 bool IsReusable
{
得到{返回真； }
}

公共无效ProcessRequest（HttpContext上下文）
{
var 段 = context.Request.Url.Segments;
var request=segments[segments.Length - 1];

context.Response.Expires = -1;

开关（请求）
{
案例“data.lst”：
this.ProcessDataRequest(上下文);
返回;
}
}

结束区域

}

我就是这样打电话的。

this.client = new WebClient();
this.client.DownloadProgressChanged += this.OnProgressChanged;
this.client.OpenReadCompleted += this.OnDataAvailable;
this.client.OpenReadAsync(new Uri("../data.lst?viewerID=viewer", UriKind.Relative), "GET");
但发布后在 IIS 7 中不会调用 ProcessRequest(HttpContext context) 方法。
请回复此帖子。提前致谢。

原文

I am working using custom IHttpHandler in my application. It is working fine in IIS 5. But now we are migrating to IIS 7 so we bought 2008 R2 server. Here it is not working. Kindly Help. you can reach me in [email protected]. Thanks in advance.
This is my Custom Handler Code :

public class WebRequestHandler : IHttpHandler, IRequiresSessionState
{
private void ProcessDataRequest(HttpContext context)
{
Controller controller = new Controller();
controller.ProcessDataRequest(context);
}

region IHttpHandler Members

public bool IsReusable
{
get { return true; }
}

public void ProcessRequest(HttpContext context)
{
var segments = context.Request.Url.Segments;
var request = segments[segments.Length - 1];

context.Response.Expires = -1;

switch (request)
{
case "data.lst":
this.ProcessDataRequest(context);
return;
}
}

endregion

}

And i am calling like this.

this.client = new WebClient();
this.client.DownloadProgressChanged += this.OnProgressChanged;
this.client.OpenReadCompleted += this.OnDataAvailable;
this.client.OpenReadAsync(new Uri("../data.lst?viewerID=viewer", UriKind.Relative), "GET");

But the ProcessRequest(HttpContext context) method is not called in IIS 7 after publishing.

Kindly Reply to this post. Thanks in advance.
