Each instance of QueryFormHandler must be configured by setting, at a minimum, these two properties:

The form handler components mentioned in the previous section are preconfigured with settings for these properties. You should not need to change these values. However, if you create your own form handler components, be sure to set these properties on them.

In addition, the form handlers have properties that you can set to enable client-side processing of the request and response objects. These properties are described in Processing the Request and Response.
