-/**
- * HTTP implementation of the TTransport interface. Used for working with a
- * Thrift web services implementation (using for example TServlet).
- *
- * This class offers two implementations of the HTTP transport.
- * One uses HttpURLConnection instances, the other HttpClient from Apache
- * Http Components.
- * The chosen implementation depends on the constructor used to
- * create the THttpClient instance.
- * Using the THttpClient(String url) constructor or passing null as the
- * HttpClient to THttpClient(String url, HttpClient client) will create an
- * instance which will use HttpURLConnection.
- *
- * When using HttpClient, the following configuration leads to 5-15%
- * better performance than the HttpURLConnection implementation:
- *
- * http.protocol.version=HttpVersion.HTTP_1_1
- * http.protocol.content-charset=UTF-8
- * http.protocol.expect-continue=false
- * http.connection.stalecheck=false
- *
- * Also note that under high load, the HttpURLConnection implementation
- * may exhaust the open file descriptor limit.
- *
- * @see <a href="https://issues.apache.org/jira/browse/THRIFT-970">THRIFT-970</a>
