configuration attributes on the instantiated LogFactory instance. Once an implementation class name is selected, the corresponding class is loaded from the current Thread context class loader (if there is one), or from the class loader that loaded the LogFactory class itself otherwise. This allows a copy of commons-logging.jar to be shared in a multiple class loader environment (such as a servlet container), but still allow each web application to provide its own LogFactory implementation, if it so desires....

    WatchedCreatorLoader loader = new WatchedCreatorLoader();
    LoadingCache<String, Integer> cache =
        CacheBuilder.newBuilder()
            .expireAfterWrite(EXPIRING_TIME, MILLISECONDS)
            .removalListener(removalListener)
            .ticker(ticker)
            .build(loader);
    checkExpiration(cache, loader, ticker, removalListener);
  }

    IdentityLoader<Object> loader = identityLoader();
    for (int i = 1; i < 1000; i++) {
      LoadingCache<Object, Object> cache = CacheBuilder.newBuilder().maximumSize(i).build(loader);
      assertEquals(i, CacheTesting.getTotalSegmentSize(cache));
    }
  }

  public void testEviction_setMaxSegmentWeight() {
    IdentityLoader<Object> loader = identityLoader();
    for (int i = 1; i < 1000; i++) {

This is done through standard HTTP/2 pooling.
The pooling is keyed off the `{source identity, destination identity, destination ip}`.

### Headers

Ztunnel uses the following well-known headers in HBONE:
