[Javascript] cache ajax

[Terry Riegel]

Hello All,

I am getting into a new project and would like to cache my ajax  
requests into a global variable.

Any ideas on how I might be able to do this?

I have the following function

  function showcat()
    {
      var category = this.id;

      var pars = '?ajaxrequest='+category+'&returndiv=maincategorydiv';
      $('maincategorydiv').innerHTML='<img src="/newsite/images/ 
spinner.gif" width="24" height="24" alt="loading" />';

      var myAjax = new Ajax.Updater('maincategorydiv', this.ajax, 
{method: 'get', parameters: pars,
                       onComplete: function(transport){accordion = new  
Accordion(category+"-accordion", 3);}

});


    }


What I would like to do is set category to the html returned by my  
ajax call

prodcat01=returned results

Make sense?

Thanks,

Terry
