jquery ajax calls & microsoft internet explorer issues

jquery ajax calls & microsoft internet explorer issues

can anyone summarize the issues with jquery ajax calls with IE and what the workarounds are?

I'm having users complain about issues of an ajax call not working, however, I've been unable to reproduce this or see the error myself.  Works fine in firefox/safari/chrome. I have windows7 + IE8/IE7 to test and that works.

My call looks like this...
var data = {trainer_class:trainer_class,monster_type:monster_type};
var d = new Date();
var args = { type:"POST",url:"/bamo/api/init_trainer/?_requestno="+d.getTime(),data:data,dataType: "json",cache:false,complete:done};
$.ajax(args);

I added the _requestno parameter because i read that IE does some smart caching of ajax calls, but, that didn't solve the problem.

any help would be most appreciated!

thanks,

ben
