据了解 Flex 技术，Flex 客户端连接到 Flex 服务器来检索业务信息。这是客户端返回原始服务器的唯一允许的连接吗？或者 Flex 客户端也可以打开与运行 BlazeDS 的其他服务器的辅助连接消息交换？ （这可能提供负载平衡和跨平台开发的选项）。
更新：感谢您的回答！我发现此页面链接到跨域策略文件规范：

As far as In understand the Flex technology, a Flex client connects to a Flex server to retrieve business information. Is this the only allowed connection for the client, back to the originating server? Or can a Flex client also open a secondary connection to a different server wich runs BlazeDS for message exchange? (This might offer an option for load balancing and cross-platform development).
Update: thanks for the answer! I have found this page which links to the Cross-domain policy file specification:

是，Flex 客户端可以连接到各种服务器，包括 BlazeDS。可能阻止客户端连接到 BlazeDS 服务器的是 crossdomain.xml，这是托管在服务器上的连接策略文档。
我对您的问题有一个担忧，那就是使用术语“Flex 服务器”。这是人们在 2005 年左右谈论 Flex 1 时所谈论的事情！ Adobe 现在使用 Flex 4，一些相关的服务器技术/平台/软件/协议包括 BlazeDS、Red5< /strong>, FMS LiveCycle 数据服务, JSON, JSON google.ch/search?sourceid=chrome&ie=UTF-8&q=amf3" rel="nofollow noreferrer">AMF3 等
Yes, a Flex client can connection to a variety of servers, including BlazeDS. What could prevent a client from conenctiong to a BlazeDS server is the crossdomain.xml, which is a connection policy document hosted on the server.
I've got one concern about your question, and that is using the term 'Flex server'. That was something folks talked about with Flex 1, circa 2005! Adobe is now on Flex 4, and some relevant server technologies/platforms/software/protocols of interest are BlazeDS, Red5, FMS LiveCycle Data Services, JSON, AMF3, etc.
如果 BlazeDS 是您的主要服务器端端点，并且您的主要目标是负载平衡，那么您可能需要探索 BlazeDS 的集群功能 - http://livedocs.adobe.com/blazeds/1/blazeds_devguide/help.html?content=services_clustering_1.html。
If BlazeDS is your main server side endpoint and your primary goal is load balancing then you may want to explore the clustering capabilities of BlazeDS -- http://livedocs.adobe.com/blazeds/1/blazeds_devguide/help.html?content=services_clustering_1.html.
