/**
 * Creates a new fetcher for fetching HTTP objects.  Not really suitable

 * @param maxObjSize          Maximum size, in bytes, of the object we will fetch, 0 if no limit..
 * @param connectionTimeoutMs timeout, in milliseconds, for connecting to hosts.
 * @param readTimeoutMs       timeout, in millseconds, for unresponsive connections
 * @param basicHttpFetcherProxy The http proxy to use.
