/**
 * Opens a URL. It can be a simple URL or one which requires basic
 * authentication.//  ww w  . ja v a  2s .  co m
 * <p/>
 * Tries to access the given URL. If http response is either
 * {@code HttpStatus.SC_UNAUTHORIZED} or
 * {@code HttpStatus.SC_PROXY_AUTHENTICATION_REQUIRED}, asks for
 * login/password and tries to authenticate into proxy server and/or URL.
 * <p/>
 * This implementation relies on the Apache Http Client due to its
 * capabilities of proxy/http authentication. <br/>
 * Proxy configuration is determined by {@link ProxySelectorRoutePlanner} using the JVM proxy
 * settings by default.
 * <p/>
 * For more information see: <br/>
 * - {@code http://hc.apache.org/httpcomponents-client-ga/} <br/>
 * - {@code http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/conn/ProxySelectorRoutePlanner.html}
 * <p/>
 * There's a very simple realm cache implementation.
 * Login/Password for each realm are stored in a static {@link Map}.
 * Before asking the user the method verifies if the information is already
 * available in the memory cache.
 *
 * @param url                   the URL string to be opened.
 * @param needsMarkResetSupport Indicates the caller <em>must</em> have an input stream that
 *                              supports the mark/reset operations (as indicated by {@link InputStream#markSupported()}.
 *                              Implementation detail: If the original stream does not, it will be fetched and wrapped
 *                              into a {@link ByteArrayInputStream}. This can only work sanely if the resource is a
 *                              small file that can fit in memory. It also means the caller has no chance of showing
 *                              a meaningful download progress. If unsure, callers should set this to false.
 * @param monitor               {@link ITaskMonitor} to output status.
 * @param headers               An optional array of HTTP headers to use in the GET request.
 * @return Returns a {@link Pair} with {@code first} holding an {@link InputStream}
 * and {@code second} holding an {@link HttpResponse}.
 * The returned pair is never null and contains
 * at least a code; for http requests that provide them the response
 * also contains locale, headers and an status line.
 * The input stream can be null, especially in case of error.
 * The caller must only accept the stream if the response code is 200 or similar.
 * @throws IOException             Exception thrown when there are problems retrieving
 *                                 the URL or its content.
 * @throws CanceledByUserException Exception thrown if the user cancels the
 *                                 authentication dialog.
