- * Multi-threaded transfers sharing a single connection pool
- * </DESC>
- *
- * This example fires up NUM_THREADS threads and in each single thread, it
- * downloads the same fixed URL a URL_ITERATIONS number of times. The received
- * data is just thrown away. It sets up a single shared object that holds the
- * connection cache and all easy handles in all threads share that same cache.
- *
- * This example uses pthreads for threads and mutexes, but should be easy to
- * modify to use different thread/mutex system should you want to.
