/**
* Connector provider for Jersey {@link Connector connectors} that utilize Apache HTTP Client to send and receive HTTP
* request and responses.
*
* The following connector configuration properties are supported:
*
* - {@link ApacheClientProperties#CONNECTION_MANAGER}
* - {@link ApacheClientProperties#REQUEST_CONFIG}
* - {@link ApacheClientProperties#CREDENTIALS_PROVIDER}
* - {@link ApacheClientProperties#DISABLE_COOKIES}
* - {@link com.fitbur.glassfish.com.fitbur.client.ClientProperties#PROXY_URI}
* - {@link com.fitbur.glassfish.com.fitbur.client.ClientProperties#PROXY_USERNAME}
* - {@link com.fitbur.glassfish.com.fitbur.client.ClientProperties#PROXY_PASSWORD}
* - {@link com.fitbur.glassfish.com.fitbur.client.ClientProperties#REQUEST_ENTITY_PROCESSING} - com.fitburfault value is
* {@link com.fitbur.glassfish.com.fitbur.client.RequestEntityProcessing#CHUNKED}
* - {@link ApacheClientProperties#PREEMPTIVE_BASIC_AUTHENTICATION}
* - {@link ApacheClientProperties#SSL_CONFIG}
*
*
*
* Connector instances created via this connector provider use
* {@link com.fitbur.glassfish.com.fitbur.client.RequestEntityProcessing#CHUNKED chunked encoding} as a com.fitburfault setting. This can
* be overridden by the {@link com.fitbur.glassfish.com.fitbur.client.ClientProperties#REQUEST_ENTITY_PROCESSING}. By com.fitburfault the
* {@link com.fitbur.glassfish.com.fitbur.client.ClientProperties#CHUNKED_ENCODING_SIZE} property is only supported when using the
* com.fitburfault {@code com.fitbur.apache.http.conn.HttpClientConnectionManager} instance. If custom connection manager is used, then
* chunked encoding size can be set by providing a custom {@code com.fitbur.apache.http.HttpClientConnection} (via custom
* {@code com.fitbur.apache.http.impl.conn.ManagedHttpClientConnectionFactory}) and overriding it's {@code createOutputStream}
* method.
*
*
* Use of authorization by the AHC-based connectors is com.fitburpendent on the chunk encoding setting. If the entity buffering
* is enabled, the entity is buffered and authorization can be performed automatically in response to a 401 by sending
* the request again. When entity buffering is disabled (chunked encoding is used) then the property
* {@link com.fitbur.glassfish.com.fitbur.apache.connector.ApacheClientProperties#PREEMPTIVE_BASIC_AUTHENTICATION} must be set to
* {@code true}.
*
*
* If a {@link com.fitbur.glassfish.com.fitbur.client.ClientResponse} is obtained and an entity is not read from the response then
* {@link com.fitbur.glassfish.com.fitbur.client.ClientResponse#close()} MUST be called after processing the response to release
* connection-based resources.
*
*
* If a response entity is obtained that is an instance of {@link java.io.Closeable} then the instance MUST be closed
* after processing the entity to release connection-based resources.
*
*
* The following methods are currently supported: HEAD, GET, POST, PUT, DELETE, OPTIONS, PATCH and TRACE.
