Examples of HttpURLConnection

com.canoo.webtest.extension.applet.runner.http.HttpURLConnection
Implementation note.
- the class assume that the typical usage is to just {@link #addRequestProperty(String,String) add} or {@link #setRequestProperty(String,String) set} request properties, andthat asking for the {@link #getRequestProperties()} list of request properties is a rare opportunity.
- There is a single cookie jar for all http connection from a jvm.

java.net.HttpURLConnection
3.org/pub/WWW/Protocols/"> the spec for details.
Each HttpURLConnection instance is used to make a single request but the underlying network connection to the HTTP server may be transparently shared by other instances. Calling the close() methods on the InputStream or OutputStream of an HttpURLConnection after a request may free network resources associated with this instance but has no effect on any shared persistent connection. Calling the disconnect() method may close the underlying socket if a persistent connection is otherwise idle at that time. @see java.net.HttpURLConnection#disconnect() @since JDK1.1
sun.net.www.protocol.http.HttpURLConnection
A class to represent an HTTP connection to a remote object.
