Thread-safe HTTP transport based on the Apache HTTP Client library.
Implementation is thread-safe, as long as any parameter modification to the Apache HTTP Client is only done at initialization time. For maximum efficiency,
applications should use a single globally-shared instance of the HTTP transport.

newDefaultHttpClient()\n\nCreates a new instance of the Apache HTTP client that is used by the [#Apache5HttpTransport()](/java/docs/reference/google-http-client/latest/com.google.api.client.http.apache.v5.Apache5HttpTransport#com_google_api_client_http_apache_v5_Apache5HttpTransport_Apache5HttpTransport__) constructor.\n\nSettings:\n\n- The client connection manager is set to PoolingHttpClientConnectionManager.\n- The retry mechanism is turned off using HttpClientBuilder#disableAutomaticRetries().\n- Redirects are turned off using HttpClientBuilder#disableRedirectHandling.\n- The route planner uses SystemDefaultRoutePlanner with ProxySelector#getDefault(), which uses the proxy settings from [system\n properties](https://docs.oracle.com/javase/8/docs/api/java/net/doc-files/net-properties.html).\n\n### newDefaultHttpClientBuilder()\n\n public static HttpClientBuilder newDefaultHttpClientBuilder()\n\nCreates a new Apache HTTP client builder that is used by the [#Apache5HttpTransport()](/java/docs/reference/google-http-client/latest/com.google.api.client.http.apache.v5.Apache5HttpTransport#com_google_api_client_http_apache_v5_Apache5HttpTransport_Apache5HttpTransport__)\nconstructor.\n\nSettings:\n\n- The client connection manager is set to PoolingHttpClientConnectionManager.\n- The retry mechanism is turned off using HttpClientBuilder#disableAutomaticRetries().\n- Redirects are turned off using

Apache5HttpTransport()\n\nConstructor that uses [#newDefaultHttpClient()](/java/docs/reference/google-http-client/latest/com.google.api.client.http.apache.v5.Apache5HttpTransport#com_google_api_client_http_apache_v5_Apache5HttpTransport_newDefaultHttpClient__) for the Apache HTTP client.\n\n### Apache5HttpTransport(HttpClient httpClient)\n\n public Apache5HttpTransport(HttpClient httpClient)\n\nConstructor that allows an alternative Apache HTTP client to be used.\n\nIf you choose to provide your own Apache HttpClient implementation, be sure that\n\n- HTTP version is set to 1.1.\n- Retries are disabled (google-http-client handles retries).\n\n### Apache5HttpTransport(HttpClient httpClient, boolean isMtls)\n\n public Apache5HttpTransport(HttpClient httpClient, boolean isMtls)\n\n[Beta](/java/docs/reference/google-http-client/latest/com.google.api.client.util.Beta) \n\nConstructor that allows an alternative CLoseable Apache HTTP client to be used.\n\nIf you choose to provide your own Apache HttpClient implementation, be sure that\n\n- HTTP version is set to 1.1.\n- Retries are disabled (google-http-client handles retries).\n- Redirects are disabled (google-http-client handles retries).\n\nMethods\n-------\n\n### buildRequest(String method, String url)\n\n protected Apache5HttpRequest buildRequest(String method, String url)\n\nBuilds a low level HTTP request for the given HTTP method.\n\n**Overrides** \n[HttpTransport.buildRequest(String method, String url)](/java/docs/reference/google-http-client/latest/com.google.api.client.http.HttpTransport#com_google_api_client_http_HttpTransport_buildRequest_java_lang_String_java_lang_String_)\n\n### getHttpClient()\n\n public HttpClient getHttpClient()\n\nReturns the Apache HTTP client.\n\n### isMtls()\n\n public boolean isMtls()\n\nReturns if the underlying HTTP client is mTLS.\n\n**Overrides** \n[HttpTransport.isMtls()](/java/docs/reference/google-http-client/latest/com.google.api.client.http.HttpTransport#com_google_api_client_http_HttpTransport_isMtls__)\n\n### shutdown()\n\n public void shutdown()\n\nGracefully shuts down the connection manager and releases allocated resources. This closes all\nconnections, whether they are currently used or not.\n**Overrides** \n[HttpTransport.shutdown()](/java/docs/reference/google-http-client/latest/com.google.api.client.http.HttpTransport#com_google_api_client_http_HttpTransport_shutdown__)\n\n### supportsMethod(String method)\n\n public boolean supportsMethod(String method)\n\nReturns whether a specified HTTP method is supported by this transport.\n\nDefault implementation returns true if and only if the request method is `\"DELETE\"`,\n`\"GET\"`, `\"POST\"`, or `\"PUT\"`. Subclasses should override.\n\n**Overrides** \n[HttpTransport.supportsMethod(String method)](/java/docs/reference/google-http-client/latest/com.google.api.client.http.HttpTransport#com_google_api_client_http_HttpTransport_supportsMethod_java_lang_String_)"]]
