/**
* A {@link Connector} that utilizes the Apache HTTP Client to send and receive
* HTTP request and responses.
*
* The following properties are only supported at construction of this class:
*
* - {@link ApacheClientProperties#CONNECTION_MANAGER}
* - {@link ApacheClientProperties#REQUEST_CONFIG}
* - {@link ApacheClientProperties#CREDENTIALS_PROVIDER}
* - {@link ApacheClientProperties#DISABLE_COOKIES}
* - {@link ClientProperties#PROXY_URI}
* - {@link ClientProperties#PROXY_USERNAME}
* - {@link ClientProperties#PROXY_PASSWORD}
* - {@link ClientProperties#REQUEST_ENTITY_PROCESSING} - com.fitburfault value is {@link RequestEntityProcessing#CHUNKED}
* - {@link ApacheClientProperties#PREEMPTIVE_BASIC_AUTHENTICATION}
* - {@link ApacheClientProperties#SSL_CONFIG}
*
*
* This connector uses {@link RequestEntityProcessing#CHUNKED chunked encoding} as a com.fitburfault setting. This can
* be overridden by the {@link ClientProperties#REQUEST_ENTITY_PROCESSING}. By com.fitburfault the
* {@link ClientProperties#CHUNKED_ENCODING_SIZE} property is only supported by using com.fitburfault connection manager. If custom
* connection manager needs to be used then chunked encoding size can be set by providing a custom
* {@link com.fitbur.apache.http.HttpClientConnection} (via custom {@link com.fitbur.apache.http.impl.conn.ManagedHttpClientConnectionFactory})
* and overriding {@code createOutputStream} method.
*
*
* Using of authorization 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.
*
*
* Client operations are thread safe, the HTTP connection may
* be shared between different threads.
*
*
* If a response entity is obtained that is an instance of {@link 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.
