Successive calls to this method change the setting and affect the default value for all future connections of that protocol. The protocol name is case insensitive. Parameters: protocol - the protocol to set the default for defaultVal - whether caching is enabled by default for the given protocol...

http.maxConnections=<int>(默认值:5),每个目标host缓存socket连接的最大数。 当在HttpURLConnection的header中加入Connection: close,则此连接不会启用keepAlive 如果想启用keepAlive,程序请求完毕后必须调用HttpURLConnection.getInputStream().close() (此操作用于归还长连接给缓存,下次同host:port的请求重用底层...
HttpClient是个很不错的开源框架,封装了访问http的请求头,参数,内容体,响应等等, HttpURLConnection是java的标准类,什么都没封装,用起来太原始,不方便,比如重访问的自定义,以及一些高级功能等。 URLConnection HTTPClient Proxies and SOCKS Authorization Methods Headers Automatic Redirection Handling Persistent Connection...
java.net.URL类里面的openConnection方法: public URLConnection openConnection(Proxy proxy){ … return handler.openConnection(this, proxy); Handler是sun.net.www.protocol.http.Handler.java类,继承java.net. URLStreamHandler.java类,用来处理http连接请求响应的。
To reduce latency, this class may reuse the same underlying Socket for multiple request/response pairs. As a result, HTTP connections may be held open longer than necessary. Calls to #disconnect() may return the socket to a pool of connected sockets. ...

http.maxConnections属性可以用于控制与每个服务器保持多少个空闲连接。 默认情况: 默认情况下,HttpURLConnection 的实现请求,服务器将数据使用Gzip压缩后再返回,HttpUrlConnection会自动解压数据通过回调getInputStream(). 在这种情况下,Content-Encoding 和Content-Length response headers 是清除的。
最近有个需求需要对于获取URL页面进行host绑定并且立即生效,在java里面实现可以用代理服务器来实现:因为在测试环境下可能需要通过绑定来访问测试环境的应用 实现代码如下: public static String getResponseText(String queryUrl,String host,String ip) {
.java***/ public HttpConnection (HttpConnection.Address address, int connectTimeout) throws IOException { //首先尝试重用现有的HTTP连接 synchronized (connectionPool) { List<HttpConnection> connections = connectionPool.get(address); if (connections != null) { while (!connections.isEmpty()) ...
