setRequestHeader and If-Modified-Since doesnt reply a 304 status

[Marco Schierhorn]

I cant use setRequestHeader with "If-Modified-Since" to get back at 304 Status.
I want to use this for storing images and xml files on the device.
And everytime the xml or the image is requested by the application it should check if a newer version is found on the server.
Im sending the date "Mon, 19 Jul 2010 11:20:22 GMT"
And im receiving the date "Mon, 19 Jul 2010 10:20:17 GMT" from the server.
Usually it should work and return a 304 status.

if (Titanium.Network.online)
{
      var c = Titanium.Network.createHTTPClient();
      if (c.status == 304)
      {
        // XML File not necessary - Clientlog File is newer
        console.log('Use Client XML File - is newer than the server XML');
        fn_end(file_obj);
        return;
      }
      // ...here will follow some code to store the files on the device
ￜ
      c.open('GET', url);
      c.setRequestHeader("If-Modified-Since", "Mon, 19 Jul 2010 11:20:22 GMT");
      c.send();
}

Marco,

We don't use this group for support. It'd be best to move it over to
the Q&A section at http://developer.appcelerator.com

The status code won't until you call send(). You could then check the
status in your readyStateChange handler.
