Learn how to improve performance by having ADF requests send HTTP requests only for changed values, speeding up the server. by Andrejus Baranovskis

Recently, I came across a property called oracle.adf.view.rich.POSTBACK_PAYLOAD_TYPE. This property helps to optimize postback payload size. It is described in ADF Faces configuration section A.2.3.16 Postback Payload Size Optimization. ADF partial requests execute an HTTP post with values from all fields included. When the postback property is set to dirty, it will include only changed values in the HTTP post. As result, the server will get only changed attributes. Potentially, this can reduce server time processing and make the HTTP request size smaller. This can be especially important for large forms with many fields.

Let’s take a look at an example. After clicking on any button in the form, go to the network monitor and study the Form Data section. You will see IDs and values for all fields included in the UI. All fields are submitted with an HTTP request by default, even if these fields were not changed: Read the complete article here.
