/** * Defines the HTTP Client and WebSocket APIs. * <p> * <b id="httpclientprops">System properties used by the java.net.http API</b> * <p> * The following is a list of system networking properties used by the java.net.http * client implementation in the JDK. Any properties below that take a numeric value * assume the default value if given a string that does not parse as a number. * Unless otherwise specified below, all values can be set in the {@code conf/net.properties} * file. In all cases, values can be specified as system properties on the command line, * in which case, any value in {@code conf/net.properties} is overridden. No guarantee is * provided that property values can be set programatically with {@code System.setProperty()}. * Other implementations of this API may choose not to support these properties. * <ul> * <li><p><b>{@systemProperty jdk.httpclient.allowRestrictedHeaders}</b> (default: see below)<br> * A comma-separated list of normally restricted HTTP header names that users may set in HTTP * requests or by user code in HttpRequest instances. By default, the following request * headers are not allowed to be set by user code: connection, content-length, expect, host, * and upgrade. You can override this behavior with this property. The names are case-insensitive * and whitespace is ignored. Note that this property is intended for testing and not for * real-world deployments. Protocol errors or other undefined behavior are likely to occur * when using this property. There may be other headers that are restricted from being set * depending on the context. This includes the "Authorization" header when the relevant * HttpClient has an authenticator set. These restrictions cannot be overridden by this * property. * </li> * <li><p><b>{@systemProperty jdk.httpclient.bufsize}</b> (default: 16384 bytes or 16 kB)<br> * The size to use for internal allocated buffers in bytes. * </li> * <li><p><b>{@systemProperty jdk.httpclient.connectionPoolSize}</b> (default: 0)<br> * The maximum number of connections to keep in the HTTP/1.1 keep alive cache. A value of 0 * means that the cache is unbounded. * </li> * <li><p><b>{@systemProperty jdk.httpclient.connectionWindowSize}</b> (default: 2^26)<br> * The HTTP/2 client connection window size in bytes. The maximum size is 2^31-1. This value * cannot be smaller than the stream window size, which can be configured through the * {@code jdk.httpclient.windowsize} system property. * </li> * <li><p><b>{@systemProperty jdk.httpclient.disableRetryConnect}</b> (default: false)<br> * Whether automatic retry of connection failures is disabled. If false, then retries are * attempted (subject to the retry limit). * </li> * <li><p><b>{@systemProperty jdk.httpclient.enableAllMethodRetry}</b> (default: false)<br> * Whether it is permitted to automatically retry non-idempotent HTTP requests. * </li> * <li><p><b>{@systemProperty jdk.httpclient.enablepush}</b> (default: 1)<br> * Whether HTTP/2 push promise is enabled. A value of 1 enables push promise; a value of 0 * disables it. * </li> * <li><p><b>{@systemProperty jdk.httpclient.hpack.maxheadertablesize}</b> (default: 16384 or * 16 kB)<br> The HTTP/2 client maximum HPACK header table size in bytes. * </li> * <li><p><b>{@systemProperty jdk.httpclient.HttpClient.log}</b> (default: none)<br> * Enables high-level logging of various events through the {@linkplain java.lang.System.Logger * Platform Logging API}. The value contains a comma-separated list of any of the * following items: * <ul> * <li>errors</li> * <li>requests</li> * <li>headers</li> * <li>content</li> * <li>frames</li> * <li>ssl</li> * <li>trace</li> * <li>channel</li> * </ul><br> * You can append the frames item with a colon-separated list of any of the following items: * <ul> * <li>control</li> * <li>data</li> * <li>window</li> * <li>all</li> * </ul><br> * Specifying an item adds it to the HTTP client's log. For example, if you specify the * following value, then the Platform Logging API logs all possible HTTP Client events:<br> * "errors,requests,headers,frames:control:data:window,ssl,trace,channel"<br> * Note that you can replace control:data:window with all. The name of the logger is * "jdk.httpclient.HttpClient", and all logging is at level INFO. * </li> * <li><p><b>{@systemProperty jdk.httpclient.keepalive.timeout}</b> (default: 30)<br> * The number of seconds to keep idle HTTP connections alive in the keep alive cache. This * property applies to both HTTP/1.1 and HTTP/2. The value for HTTP/2 can be overridden * with the {@code jdk.httpclient.keepalive.timeout.h2 property}. * </li> * <li><p><b>{@systemProperty jdk.httpclient.keepalive.timeout.h2}</b> (default: see * below)<br>The number of seconds to keep idle HTTP/2 connections alive. If not set, then the * {@code jdk.httpclient.keepalive.timeout} setting is used. * </li> * <li><p><b>{@systemProperty jdk.httpclient.maxframesize}</b> (default: 16384 or 16kB)<br> * The HTTP/2 client maximum frame size in bytes. The server is not permitted to send a frame * larger than this. * </li> * <li><p><b>{@systemProperty jdk.httpclient.maxstreams}</b> (default: 100)<br> * The maximum number of HTTP/2 push streams that the client will permit servers to open * simultaneously. * </li> * <li><p><b>{@systemProperty jdk.httpclient.receiveBufferSize}</b> (default: operating system * default)<br>The HTTP client <a href="../java.base/java/net/StandardSocketOptions.html#SO_RCVBUF"> * socket receive buffer size</a> in bytes. * </li> * <li><p><b>{@systemProperty jdk.httpclient.redirects.retrylimit}</b> (default: 5)<br> * The maximum number of attempts to send a HTTP request when redirected or any failure occurs * for any reason. * </li> * <li><p><b>{@systemProperty jdk.httpclient.websocket.writeBufferSize}</b> (default: 16384 * or 16kB)<br>The buffer size used by the web socket implementation for socket writes. * </li> * <li><p><b>{@systemProperty jdk.httpclient.windowsize}</b> (default: 16777216 or 16 MB)<br> * The HTTP/2 client stream window size in bytes. * </li> * <li><p><b>{@systemProperty jdk.httpclient.auth.retrylimit}</b> (default: 3)<br> * The number of attempts the Basic authentication filter will attempt to retry a failed * authentication. * </li> * <li><p><b>{@systemProperty jdk.httpclient.sendBufferSize}</b> (default: operating system * default)<br>The HTTP client socket * <a href="../java.base/java/net/StandardSocketOptions.html#SO_SNDBUF">send buffer size</a>. * Values less than or equal to zero are ignored. * </li> * <li><p><b>{@systemProperty jdk.internal.httpclient.disableHostnameVerification}</b> (default: * false)<br>If true (or set to an empty string), hostname verification in SSL certificates * is disabled. This is a system property only and not available in {@code conf/net.properties}. * It is provided for testing purposes only. * </li> * <li><p><b>{@systemProperty jdk.http.auth.proxying.disabledSchemes}</b> (default: see * conf/net.properties)<br>A comma separated list of HTTP authentication scheme names, * that are disallowed for use by the HTTP client implementation, for HTTP proxying. * </li> * <li><p><b>{@systemProperty jdk.http.auth.tunneling.disabledSchemes}</b> (default: see * conf/net.properties)<br>A comma separated list of HTTP authentication scheme names, that * are disallowed for use by the HTTP client implementation, for HTTP CONNECT tunneling. * </li> * </ul> * @moduleGraph * @since 11
