Hi Raffaele,
I think the WMS request is always sent. One idea could be that you add some
if/else inside the current if loop or elseif to prevent sending the request,
something like:
getfeatureinfo: function(event) { if(event.features.length > 0)
{if (url =! "something") {//statement here to prevent to be sent}else
map.addPopup(new OpenLayers.Popup.FramedCloud(
"sostegno",
map.getLonLatFromPixel(event.xy), null,
event.text, null,
true )); } }
}
the above is untested, it's just one idea about it. Perhaps googling around
will help you to find some more ideas, try in stackoverflow.com.
Hope this helps,
Gery

OpenLayers.Popup.FramedCloud
Raffaele, That is the way I prevent the popup from showing up when there are
not any features. I am not sure how to prevent the getfeatureinfo request from
being made in that situation. Someone with more experience than myself will
need to address that issue. Jerome From:

Subject: Re: [OpenLayers-Users] WFSGetFeatureInfo and
OpenLayers.Popup.FramedCloud It helps but the WMS request is sent anyway, but
apart from that it doesn't workevent.features.length=0 but the popup doesn't
show up Here is my code snippet getfeatureinfo: function(event) {
if(event.features.length > 0) { map.addPopup(new
OpenLayers.Popup.FramedCloud( "sostegno",
map.getLonLatFromPixel(event.xy),
null, event.text, null,
true )); }
} }
