Hi hijaggu;

Load balancing is actually a broad topic and can be achieved in several ways. See if this link can help you get started.

Thanks for your prompt reply Denis. Let me explain my requirement in detail. Currently we are configuring objectServer details in client side config file and Ideablade reads it from there to connect to BOS.

Instead of that I want client app to call custom implemented WCF service which can return objectServer details based on certain parameters supplied by client app in order to connect to specific BOS.

This can be useful to route the clients to different servers based on say their geographical location. We don’t want to hard code objectServer details in client app config file.

It sounds like you want to programatically change the objectServer element inside the app.config. This can be achieved by using the IdeaBladeConfig.Instance. You can look at the API for more info, but here's a small snippet showing how it works.

var ideaBladeConfig = IdeaBladeConfig.Instance;

var objectServer = ideaBladeConfig.ObjectServer;

ideaBladeConfig.ObjectServer.ClientSettings.IsDistributed = true;

if (ideaBladeConfig.ObjectServer.ServerPort != 9009) {

ideaBladeConfig.ObjectServer.ServerPort = 9009;

}

if (ideaBladeConfig.ObjectServer.RemoteBaseUrl != "http://localhost") {

ideaBladeConfig.ObjectServer.RemoteBaseUrl = "http://localhost";

}

if (ideaBladeConfig.ObjectServer.ServiceName != "EntityService.svc") {

ideaBladeConfig.ObjectServer.ServiceName = "EntityService.svc";

}
