public final class APIFilter
Maps /api requests to the appropriate .do URI. This can be thought of as the first half of a wrapper surrounding
Struts for API calls. This part of the wrapper maps request under /api to the .do URLs that Struts needs.
The second half of the wrapper is the JSON output that is generated from
/WEB-INF/templates/administrator/default/json/apiResponse.jsp and the other files it calls.
