+/**
+ * <p>Decorator adding support for compressed responses. This class sets
+ * the <code>Accept-Encoding</code> header on requests to indicate
+ * support for the <code>gzip</code> and <code>deflate</code>
+ * compression schemes; it then checks the <code>Content-Encoding</code>
+ * header on the response to uncompress any compressed response bodies.
+ * The {@link java.io.InputStream} of the entity will contain the uncompressed
+ * content.</p>
+ *
+ * <p><b>N.B.</b> Any upstream clients of this class need to be aware that
+ * this effectively obscures visibility into the length of a server
+ * response body, since the <code>Content-Length</code> header will
+ * correspond to the compressed entity length received from the server,
+ * but the content length experienced by reading the response body may
+ * be different (hopefully higher!).</p>
+ *
+ * <p>That said, this decorator is compatible with the
+ * <code>CachingHttpClient</code> in that the two decorators can be added
+ * in either order and still have cacheable responses be cached.</p>
+ *
+ * @since 4.2
+ *
+ * @deprecated (4.3) use {@link HttpClientBuilder}
