### Key Design Patterns

- **Factory**: `CrawlerClientFactory`, `ExtractorFactory` - protocol/format-specific component selection
- **Strategy**: `CrawlerClient`, `Extractor`, `Transformer` - pluggable implementations
- **Builder**: `RequestDataBuilder`, `ExtractorBuilder` - fluent construction

    if (pathname.isEmpty()) {
      return ".";
    }

    // split the path apart
    Iterable<String> components = Splitter.on('/').omitEmptyStrings().split(pathname);
    List<String> path = new ArrayList<>();

    // resolve ., .., and //
    for (String component : components) {
      switch (component) {
        case ".":
          continue;
        case "..":

### Load Balancer { #load-balancer }

When using containers, you would normally have some component **listening on the main port**. It could possibly be another container that is also a **TLS Termination Proxy** to handle **HTTPS** or some similar tool.

        // Test that all mock components are properly registered
        assertNotNull(ComponentUtil.getComponent("crawlingConfigHelper"), "CrawlingConfigHelper should be registered");
        assertNotNull(ComponentUtil.getSystemHelper(), "SystemHelper should be registered");
        assertNotNull(ComponentUtil.getFessConfig(), "FessConfig should be set");
        assertTrue("Component integration test should be fast", true);
    }

A major advantage of certificate-based authentication compared to other STS authentication methods, like OpenID Connect or LDAP/AD, is that client authentication works without any additional/external component that must be constantly available. Therefore, certificate-based authentication may provide better availability / lower operational complexity.
