To set the path, implement
#updateUrl: in your components. This will get passed a
WAUrl instance, which responds to
#addParameter:value:. Each active component gets a chance to modify it before every redirect and response.
To initialize your app, implement
initialRequest:. This will be sent at the beginning of the session, and gets passed a
WARequest instance. Typically you will want to use the information in the request to construct the root component.
WABrowser for an example.
