<?php

// This is a purely experimental module and is not yet generally useful.

// The eventual goal is to provide a json backend to fetch content and fill the current page.
// The page will be filled in on the frontend using javascript.
// At the present time this page is based on "network", but the hope is to extend to serving
// any content (wall, community, search, etc.).
// All search parameters, etc. will be managed in javascript and sent as request params.
// Security will be managed on the backend.
// There is no "pagination query", but we will manage the "current page" on the client
// and provide a link to fetch the next page - until there are no pages left to fetch.

// With the exception of complex tag and text searches, this prototype is incredibly
// fast - e.g. one or two milliseconds to fetch parent items for the current content,
// and 10-20 milliseconds to fetch all the child items.
