## Quick Start

### Prerequisites

 * either HC4 Hc4Authentication or HC5 Hc5Authentication.
 *
 * <p>This class provides a library-independent way to configure
 * HTTP authentication that works with both Apache HttpComponents 4.x
 * and 5.x clients.</p>
 *
 * <p>Example usage for Basic authentication:</p>
 * <pre>{@code
 * WebAuthenticationConfig config = new WebAuthenticationConfig();
 * config.setHost("example.com");

import org.codelibs.core.misc.Pair;
import org.codelibs.core.stream.StreamUtil;
import org.codelibs.fess.crawler.Constants;

/**
 * The Hc5FormScheme class implements the AuthScheme interface for Apache HttpComponents 5.x
 * to provide form-based authentication for HTTP clients. It handles the process of
 * obtaining a token and logging in using the provided credentials.
