问题描述
如果我有一个自定义的.browser文件，并且我想评估如果给它一个特定的用户代理，将会发生什么，是否有任何方法可以通过.NET API做到这一点?
If I have a custom .browser file, and I want to evaluate what will happen if it is given a particular User Agent, is there any way to do that through the .NET API?
我试图使用HttpBrowserCapabilites，但是我不确定如何将自定义.browser文件加载到该类中.
I was attempting to use HttpBrowserCapabilites, but I'm not sure how to load a custom .browser file into that class.
推荐答案
通常，您不必显式加载HttpBrowserCapabilities类.只要您将.browser文件放在正确的位置(在App_Browsers中)，ASP.NET就会为您加载它.
Normally, you should not have to explicitly load the HttpBrowserCapabilities class; ASP.NET will load it for you, as long as you have your .browser file in the right place (in App_Browsers).
但是，进行测试将是另一个问题.您无法从HttpApplication(global.asax)或自定义HttpModule内修改"User-Agent" HTTP标头.
However, testing it will be another problem. You can't modify the "User-Agent" HTTP Header from within either the HttpApplication (global.asax) or a custom HttpModule.
这仅留下笨拙的技术，例如使用反射来强制值，或使用外部工具(例如Fiddler).或者，如果您精通C/C ++，则可以举一个简单的ISAPI筛选器示例并对其进行修改，然后将其安装在IIS中.
This leaves only awkward techniques, such as using Reflection to force the value, or using an external tool (such as Fiddler). Alternately, if you're good with C/C++, you could take a simple example for an ISAPI filter and modify it, then install it in IIS.
