[jQuery] problem with $.ajax()

[Salvatore FUSTO]

Hi all,
i'm developing an intranet order application using many ajax calls; this app is 
fine on my pc intel pIV-2800 Mhz based, and on the internet, but when i try to 
install in on the server on the intranet, it fails.
this server has an amd athlon x64 4400+, with 2Gb RAM.
if tou test http://www.fusto.org/sangermano/index.cfm?event=taglioModelli, when 
selecting modello , my app run thre chained ajax call, completing the upper 
form, buton the amd server, only the first call is made.
this app is based on adobe cf 7.0.2 and model glue.
the ajax chain,  when selecting modello, is:

function taglie(){
 $("div#clientiMT").html("");
 $("#coloriTessutoDaTagliare").html('');
 $("#tNeeds").html('');
 $("#aMarchi").html('');
 $("#aAppendini").html('');
 $("div#coloriTessutoDaTagliare").html("");
 $("div#tNeeds").html("");
 var myMod = $("#modelliOrdinati").val();
 var theUrl = "index.cfm?event=taglie";
 $.getJSON(theUrl,{modello:myMod},function(dati){orderedTM(dati)});
}

function orderedTM(dati){
 $("#modTaglie").val(dati.TAGLIE);
 $("#modelliInCompleto").val(dati.COMPLETO);
 $("td#leTaglie").html('');
 $("td#orderedTM").html('');
 var myMod= $("#modelliInCompleto").val();
 var myUrl = "index.cfm?event=modelliInCompleto&modello=" + myMod;
 $.get(myUrl,function(dati){esplodiMC(dati)});
} 

function esplodiMC(dati){
 $("tr.modelliInCompleto").remove();
 $("#trModello").after(dati);
 var myMod= $("#modelliOrdinati").val();
 var myUrl = "index.cfm?event=TxMordinato&modello=" + myMod;
 if (myMod != "0"){
  $("td#orderedTM").html('<img src="assets/images/loader-blue.gif"');
  $("td#orderedTM").load(myUrl);
 }
} 
 
has anyone ever had a similar problem?
regards
