code: @Deprecated
      public static byte[] getContentFromUrl(String url, Proxy proxy, SSLSocketFactory factory, HostnameVerifier verifier)
      {
          return getContentFromUrl(url);
      }
docs: Anyone using the proxy calls such as this one should have that managed by the jvm with -D parameters:
  http.proxyHost
  http.proxyPort (default: 80)
  http.nonProxyHosts (should always include localhost)
  https.proxyHost
  https.proxyPort
  
  Example:  -Dhttp.proxyHost=proxy.example.org -Dhttp.proxyPort=8080 -Dhttps.proxyHost=proxy.example.org -Dhttps.proxyPort=8080 -Dhttp.nonProxyHosts=*.foo.com|localhost|*.td.afg
  Get content from the passed in URL.  This code will open a connection to
  the passed in server, fetch the requested content, and return it as a
  byte[].
  
  @param url URL to hit
  @param proxy Proxy server to create connection (or null if not needed)
  @param factory custom SSLSocket factory (or null if not needed)
  @param verifier custom Hostnameverifier (or null if not needed)
  @return byte[] of content fetched from URL.
  @deprecated As of release 1.13.0, replaced by {@link #getContentFromUrl(String)}
