Question

This is more a general caching question.

In my project I have pages with a couple ext.net 2.0 beta controls with asp.net-mvc3/razor

So for these pages, from the data I gather in firebug, I think that the browser isn’t caching the ext.axd resource files after it is restarted.

This is what I see:

1. Start Firefox, goto my page
2. All requests show 200 OK
3. If I press F5, I see all the requests as 304 Not Modified
4. Now, if I restart the browser, it goes back to Http 200 responses.

Is browser NOT caching my resources? Is there a setting or config I can employ for it to cache my resources across browser sessions?

This is what firebug looks like:

1. When I first start:
   

2. When I press F5 this is what I see:

   

   This is what an individual request looks like:

   

   When I restart the browser, I go back to (1). I get 200OK everywhere.

(1) Are the resources being cached? (2) Is there something I can do to cache it?

Answer 1

The line items on initial request are ‘black’ and fetched from original source. The items are then added to browser cache.

On subsequent requests, the items are pulled directly from cache, and coloured ‘gray’. I guess this is just a ‘feature’ of Firebug.
