Combine requests for multiple panels?
I have a nice intranet application that uses lots of FormPanels:
(Sorry for all the grey bars, cencoring all the "secret" information )
Each panel gets it data by doing a HTTP request when it's loaded, so my Firebug looks something like this:
I probably don't have to tell you this is not very nice on the server and gets quite slow if there are many tabs opened at once.
Is there any way to combine these requests somehow?
Right now the loading of the form is done in its initComponent(), but I thought about it just adding values to an array and creating another function to do a request and populate the form - but I have no idea if this is the right way or if there are better ones.
So perhaps even any examples of how to optimize the loading of many panels?

I'm not sure if it's the best way but what I've done is create a master Ext.data.Store (or whichever store) and then add a listener for the the load event. Once it loads, I can create separate stores for whatever I need.
When you are returning the data for the master store, just create an array with a separate key which holds an array or whatever you need for the separate stores.
Make any sense?Mitchell Simoens @SenchaMitch

Thanks Mitchell, this makes sense.
I was hoping for a somewhat automated way, perhaps a "pool store" where you collect the data you want to request and it is done with one request to the server or something. But as this is a really specific request, I understand that this probably doesn't exist.
I'll see if it is necessary at all.
