# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

curl4j is a simple cURL-like Java HTTP client library providing a fluent API for building HTTP requests. It's designed to be minimal with only Apache Commons IO as a dependency.

## Development Commands

### Build and Test
```bash
# Clean build and run tests
mvn clean test

# Full build with packaging

        return fessConfig.isCrawlerDocumentDuplicateTermRemoved();
    }

    /**
     * Gets the array of space character codes from configuration.
     *
     * @return array of character codes to be treated as spaces
     */
    protected int[] getSpaceChars() {
        final FessConfig fessConfig = ComponentUtil.getFessConfig();

### Fallback Mechanism

If a translation is missing in `fess_label_[locale].properties`, Fess automatically falls back to the base `fess_label.properties` (English).

### Language Code Format

Use standard locale codes:
- ISO 639-1 language codes: `en`, `ja`, `de`, `fr`, `sv`, etc.
- With region when needed: `pt_BR`, `zh_CN`, `zh_TW`, `en_IE`

### Cache Behavior

- Language items are cached for 1 hour by `SystemHelper`

        int[] codes = (int[]) propMap.get(CRAWLER_FAILURE_URL_STATUS_CODES);
        if (codes == null) {
            codes = split(getCrawlerFailureUrlStatusCodes(), ",")
                    .get(stream -> stream.filter(StringUtil::isNotBlank).mapToInt(Integer::parseInt).toArray());
            propMap.put(CRAWLER_FAILURE_URL_STATUS_CODES, codes);
        }

    protected static final String CRAWLER_CLIENTS = "crawlerClients";

    /** HTTP status code for Not Found */
    private static final int HTTP_STATUS_NOT_FOUND = 404;

    /** HTTP status code for OK */
    private static final int HTTP_STATUS_OK = 200;

    /**

     * and handles special cases like "all languages" selection.

     * @param params The search request parameters
     * @return Array of normalized language codes
     */
    public String[] getLanguages(final HttpServletRequest request, final SearchRequestParams params) {
        final SystemHelper systemHelper = ComponentUtil.getSystemHelper();

        CloseableUtil.closeQuietly(responseData);
        httpRequest.abort();
    }

    /**
     * Checks if the HTTP status code indicates a redirect.
     *
     * @param httpStatusCode The HTTP status code to check
     * @return True if the status code indicates a redirect, false otherwise
