在Azure模拟器中测试多个Web角色实例

Question

I have a web role that will run on multiple instances on Azure. It is an MVC3 app that allows users to upload multiple image files. I'm using Plupload (http://www.plupload.com/) for uploads and the files are sent on chunks to the server.

I would like to test how this works on multiple instances. So I configured my cloud service to start 2 instances of my web role and put a breakpoint in my Upload action. The problem is that all my requests are served by the first instance of the web role. I would like the requests to be balanced (but this could be an issue with how Plupload handles the upload). Is there any way to simulate that behavior?

I have to say that the load balance of the local emulator was not that "balanced". You need to try many times to ensure that it does route your request to all instances. My experience is that, even though just have 2 instances and press F5 to refresh the same page, you need about 10 - 15 times to make sure it's balanced to another instance.
