如何排除匹配在ASP.Net一个HttpHandler指定路径的东西呢？ [英] How do I exclude things that match the specified path for an HttpHandler in ASP.Net?

问题描述

我知道，如果我想为MyPage.aspx请求转到名为MyAssembly的装配MyHandler的所谓阶级，我可以将它添加到我的web.config文件：

I know that if I want to have requests for MyPage.aspx go to the class called MyHandler in the assembly called MyAssembly, I can add this to my web.config file:

<configuration>
  <system.web>
    <httpHandlers>
      <add verb="*" path="MyPage.aspx" type="MyHandler, MyAssembly"/>
  </system.web>
</configuration>

这适用于在（由）网址任何MyPage.aspx：www.mycoolsite.com/MyProject/ [SomePathHere] /MyPage.aspx

This works for any MyPage.aspx at the (made up) URL: www.mycoolsite.com/MyProject/[SomePathHere]/MyPage.aspx

如果我想这样做，每MyPage.aspx的除了的www.mycoolsite.com/MyProject/NoHandler/MyPage.aspx

What if I want to do it for every MyPage.aspx except www.mycoolsite.com/MyProject/NoHandler/MyPage.aspx

有没有办法排除从处理这条道路？

Is there a way to exclude that path from the handler?

推荐答案

您可以把它定义了一个不同的处理程序的 NoHandler 文件夹中的web.config（NOTFOUND如果你要服务器404风格等）。格式相同电流的web.config ，要覆盖类的处理器只是把唯一的元素。

You can put a web.config in the NoHandler folder that defines a different handler (NotFound if you want to server a 404 style, etc). Same format as your current web.config, just put only the elements you want to override like the handler.

下面是一个例子，如果你想在该目录404重写：

Here's an example if you want to override with a 404 in that directory:

<configuration>
 <system.web>
  <httpHandlers>
   <remove verb="*" path="MyPage.aspx" type="MyHandler, MyAssembly"/>
   <add verb="*" path="MyPage.aspx" type="MySpecialHandler, MyAssembly"/>
  </httpHandlers>
 </system.web>
</configuration>
