### [URLs](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-http-url/)

URLs (like `https://github.com/square/okhttp`) are fundamental to HTTP and the Internet. In addition to being a universal, decentralized naming scheme for everything on the web, they also specify how to access web resources.

URLs are abstract:

    /**
     * Default constructor.
     */
    public SearchBody() {
        super();
    }

    /** Name of the web crawling configuration */
    public String name;

    /** URLs to crawl */
    public String urls;

    /** Description of the web crawling configuration */
    public String description;

    }

    /**
     * Preprocesses the URI before processing the request.
     *
     * @param uri the URI to preprocess
     * @return the preprocessed URI
     * @throws CrawlerSystemException if the URI is empty
     */
    protected String preprocessUri(final String uri) {
        if (StringUtil.isEmpty(uri)) {
            throw new CrawlerSystemException("The uri is empty.");
        }

        return uri;

import jakarta.annotation.Resource;

/**
 * A response processor implementation that handles sitemaps.
 * It parses the response body as a SitemapSet, extracts URLs from the sitemaps,
 * and adds them as child URLs to be crawled.
 *
 * <p>
 * This class uses a {@link SitemapsHelper} to parse the sitemap XML or text.
 * It then iterates through the sitemaps in the SitemapSet, extracts the URL

        return getString(relativeSource, StandardCharsets.UTF_8);
    }

    /**
     * PUTs the source file (must exist as file) to target URI. The target MUST BE relative from the
     * {@link RemoteRepository#getUrl()} root.
     *
     * @throws RuntimeException If PUT fails for any reason.
     */
    void put(@Nonnull Path source, @Nonnull URI relativeTarget);
