     ** Static method for performing an HTTP request to the specified URL.<br>
     ** This method requires as second parameter a non-empty Hashtable, that should specify the URL request properties.<br>
     ** If the Hashtable is null, a MalformedUrlException is generated.<br>
     ** The Hashtable can contain the following key/values properties:<br>
     ** <ul>
     ** <li><b>HEADERS</b> (key = &quot;headers&quot;): you can specify optional additional headers in this field.<br>
     ** The corresponding value should be an Hashtable with name/value pairs for each header to add.<br>
     ** If not present the &quot;User-Agent&quot; header assumes the default value of
     ** &quot;<code>Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)</code>&quot;.<br>
     ** If not present the &quot;Connection&quot; header assumes the default value of &quot;<code>close</code>&quot;.</li>
     ** <li><b>METHOD</b> (key = &quot;method&quot;): you can specify which method to use for URL requests between
     ** &quot;GET&quot; and &quot;POST&quot; are the only ones supported for now.</li>
     ** <li><b>REQUEST PARAMETERS</b> (key = &quot;request_params&quot;): you can specify the parameters
     ** to add to the HTTP request in this field.<br> The corresponding value should be an Hashtable
     ** with name/value pairs for each parameter to add.<br> For multiple parameters use a String[] (string array)
     ** as value.</li>
     ** <li><b>COOKIES</b> (key = &quot;method&quot;): you can specify optional cookies to set in the
     ** HTTP request in this field.<br> The corresponding value should be a String[] (string array).</li>

     ** <ul>
     ** <li><b>RESPONSE CODE</b> (key = &quot;response_code&quot;): an Integer containing the HTTP response code,
     ** e.g. 404.</li>
     ** <li><b>RESPONSE MESSAGE</b> (key = &quot;response_message&quot;): a String containing the complete
     ** response message, e.g. <code>HTTP/1.1 404 Not Found<(code>.</li>
