Does anyone can help me with caching a json string in Trigger.io? I have a lot of json request for which i think its a good idea to cache them for say 1 hour for example. According to the jquery manual about $.ajax(Trigger.io points to this manual for forge.request.ajax) there is no caching for jsonp and script as a type but i’m using json here so i was hoping to do some caching on it.

I’m using the forge.request.ajax like so:

  forge.request.ajax({
    url: the_url_to_api,
    dataType: 'json',
    cache: true,
    success: function(data) {
      parsed_template = _.template( $('#sales_index_template').html(), {nowOnSale:     data.activeSales, soonOnSale: data.upcomingSales } );
      app.end_set_right_content(parsed_template);
    },
    error: function(error) {
    alert('Request for sales failed');
    }
  });

And this are my headers for the json return script in the API

  • x-powered-by PHP/5.3.15
  • Connection Keep-Alive
  • Content-Length 4294
  • Pragma cache
  • Server Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8g PHP/5.3.15
  • Content-Type application/json; charset=utf-8
  • Cache-Control max-age=3600
  • Keep-Alive timeout=5, max=100
  • Expires Tue, 28 Aug 2012 16:19:30 GMT

With the above settings there is no caching going on if i look in chromes or safaris network debugger.. Maybe someone can help me with what i’m doing wrong? or maybe somebody has a better idea for caching in Trigger.io?

Thanks in advanche!

    In a recent application I developed I cache (in memory) the resulting json until the user presses the little “refresh” icon. I guess I could add an extra user preference setting to automatically expire in x days. Also, instead of using memory I could have utilized trigger.io to save the json to disk.

    Here is the app if you want to see how I do it (Note: I committed a couple of untested tweeks this morning):

    The viewmanager.js handles most of the backbone.js model caching logic. Basically I do the usual:

    1. Is the model in the cache?
    2. If Yes, then use cached model.
    3. If No, then bind model (via json) add to cache.
    4. Use it (the returned model).
