One idea could be that you add some if/else inside the current if loop or elseif to prevent sending the request, something like:<br><br><div><div><p class="ecxMsoNormal">getfeatureinfo: function(event) {</p></div><div><p class="ecxMsoNormal"> if(event.features.length > 0) {</p><p class="ecxMsoNormal">if (url =! "something") {</p><p class="ecxMsoNormal">//statement here to prevent to be sent</p><p class="ecxMsoNormal">}</p><p class="ecxMsoNormal">else<br></p></div><div><p class="ecxMsoNormal"> map.addPopup(new OpenLayers.Popup.FramedCloud(</p></div><div><p class="ecxMsoNormal"> "sostegno",</p></div><div><p class="ecxMsoNormal"> map.getLonLatFromPixel(event.xy),</p></div><div><p class="ecxMsoNormal"> null,</p></div><div><p class="ecxMsoNormal"> event.text,</p></div><div><p class="ecxMsoNormal"> null,</p></div><div><p class="ecxMsoNormal"> true</p></div><div><p class="ecxMsoNormal"> ));</p></div><div><p class="ecxMsoNormal"> }</p></div><div><p class="ecxMsoNormal"> }</p></div><div><p class="ecxMsoNormal"> }</p></div></div><br>the above is untested, it's just one idea about it.
