Configure Underlying Clients

The service framework wraps most functionality of the underlying clients (FTPClient, HTTPClient, and so on), but you can directly configure the underlying clients when needed.

For example, if you want to cache web service calls for HTTPService, in your createRequest callback, use the getClient method to get the underlying HTTPClient object for the service and use the HTTPClient class enableCaching method to cache the request.

LocalServiceRegistry.createService("yourService", {
     createRequest: function(svc:HTTPService, args) {
          svc.client.enableCaching(1000);
[...]

Note: Make sure to use getClient and any HTTPClient methods in the createRequest callback or later callbacks, not when you get the service object from the registry. This is because the underlying HTTPclient object isn't initialized until you call the service using the createRequest object. Before calling the service, using getClient only returns null.

Cached requests are seen in the dashboard and you should see lower average execution times once caching is enabled. Cached requests are counted toward rate limits, circuit breakers, and statistics, because all of these are measured at the service level and are triggered by calls to the service.
