- Support for query parameters, headers, body (String or stream), compression, SSL configuration, proxies, and timeouts
- Automatic in-memory or on-disk caching of request/response bodies
- Synchronous and asynchronous (callback) execution
- Minimal dependencies (only Apache Commons IO)

## Installation

### Maven

Add the dependency to your `pom.xml` (replace `x.y.z` with the latest version):

```xml
<dependency>

        }

        @Override
        public void streamChat(final LlmChatRequest request, final LlmStreamCallback callback) {
            if (streamChatCapture != null) {
                streamChatCapture.capture(request, callback);
            } else {
                callback.onChunk("test response", true);
            }
        }

        @Override
        public String getName() {

        }

        UnaryOperator<String> callback = or(
                context.extraInterpolationSource()::get,
                context.systemPropertiesOverrides::get,
                systemProperties::getProperty);
        Path propertiesFile = mavenConf.resolve("maven-system.properties");
        try {
            MavenPropertiesLoader.loadProperties(systemProperties, propertiesFile, callback, false);
        } catch (IOException e) {

## Authorization Flow

- Visit <http://localhost:8080>, login will direct the user to the Google OAuth2 Auth URL to obtain a permission grant.
- The redirection URI (callback handler) receives the OAuth2 callback, verifies the state parameter, and obtains a Token.
- Using the id_token the callback handler further talks to Google OAuth2 Token URL to obtain an JWT id_token.
