如何在 VSTS2010 中禁用 WebTestRequest 的 DependentRequests 以进行第二个请求
我正在使用 Visual Studio 2010 来记录一些 Web 测试。我打算使用这些网络测试构建一些负载测试。我所针对的网站的大多数页面都有许多其他资源，例如 js、css 文件和图像。当实际用户浏览网站时，这些资源会被第一次下载，然后被浏览器缓存。下载这些资源的 GET 请求被捕获为 WebTestRequest 中的 DependentRequests
我想在负载测试中模拟这一点。当同一个虚拟用户向服务器发送第二个请求时，DependentRequests 不应发送到服务器。通过将 WebTestRequest.ProcessDepedentRequest 设置为 False，我们可以关闭向服务器发送 DependentRequests。但这即使对于第一个请求也会将其关闭，这是我不想要的。
有什么办法可以实现这一点吗？
更新
进一步思考，当我有步骤类型的负载组合时，我从 10 个虚拟用户开始，每 2 分钟后我再添加 10 个虚拟用户。现在 2 分钟后，我将拥有 20 个虚拟用户。此时，所有 20 个虚拟用户是否都被视为首次访问我的网站的新用户，还是其中 10 个（从第一个时间段开始）第二次访问我的网站，其余 10 个是第一次访问我的网站？
I'm using Visual Studio 2010 for recording some web tests. I intend to build some load tests using these web tests. Most of the pages of the website that I'm targeting have lot of other resources like js, css files and images. When an actual user is browsing the website, these resources are downloaded for the first time and then cached by the browser. The GET requests for downloading these resources are captured as DependentRequests in WebTestRequest
I want to simulate this in my load test. When the same virtual user sends second request to the server, the DependentRequests should not be sent to server. By setting WebTestRequest.ProcessDepedentRequest to False we can turn off sending the DependentRequests to server. But this would turn it off even for the first request, which I don't want.
Is there any way to achieve this?
Update
Thinking further, when I have a load mix of step type where in I start with 10 virtual users and after every 2 mins I add 10 more virtual users. Now after 2 mins, I would have 20 virtual users. At this point, are all 20 virtual users treated as new users hitting my website for the first time or 10 of these (from the first time slot) are hitting my website second time and remaining 10 hitting my website for first time?

Visual Studio 负载测试已经自动模拟浏览器缓存行为：仅为虚拟用户提取一次相关请求。
关于虚拟用户：在LoadTest运行设置中，有一个名为“新用户百分比”的设置。如果将其设置为 0，则每个新的测试迭代都将由新的虚拟用户运行，因此他们的模拟缓存将始终从空开始。
如果设置为 100，则每次新的测试迭代都将在可能的情况下重用现有的虚拟用户，因此只有在虚拟用户的第一次测试迭代中，模拟缓存才会为空，然后对于其余的测试迭代，模拟缓存将为空防止重新获取相关请求。
Visual Studio Load Tests already automatically simulate browser caching behaviour: dependent requests are only fetched once for a virtual user.
Regarding virtual users: in the LoadTest Run Settings, there is a setting called "Percentage of New Users". If this is set to 0, every new test iteration will be run by a new virtual user, and so their simulated cache will always start out empty.
If it is set to 100, every new test iteration will re-use an existing virtual user if possible, so only on a virtual user's first test iteration will the simulated cache be empty, and then for the remainder of test iterations the simulated caching will prevent the re-fetching of dependent requests.

实际上是相反的。如果将“新用户百分比”指定为 100，则意味着每次新迭代都将由新用户运行。

It's actually other way around. If you specify "Percentage of New Users" as 100 that means that every new iteration will run by new user.
