## Supported Protocols and Formats

### Protocols
- **HTTP/HTTPS**: Full web crawling support with cookies, authentication, redirects
- **File System**: Local and network file system access
- **FTP**: FTP server crawling with authentication

/**
 * Interface for SSO (Single Sign-On) authenticator implementations.
 *
 * This interface defines the contract for SSO authentication providers that can be
 * integrated with Fess. Implementations handle specific SSO protocols like SAML,
 * OAuth, SPNEGO, or other authentication mechanisms. Each authenticator is responsible
 * for obtaining login credentials, resolving user information, and managing SSO

Blocking APIs may be inefficient because you hold a thread idle while waiting on the network. Threads are expensive because they have both a memory overhead and a context-switching overhead.
