Hey everybody,

I'm using CI's query cache feature and that's working fine, but I am having some issues with browser caching. I read some older threads like this one but haven't been able to find anything that works so far.

We've got some different data coming in from several mysql tables that are updated a few times a day. However, when you go to that page, more often than not an older entry is there and you need to refresh to get something new, and I'd like to have the content just show up.

What I've got in place in the controller:

Code:
$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");

$this->output->set_header("Pragma: no-cache");

What's in the header of the HTML document:

Code:
&lt;meta http-equiv="Pragma" content="no-cache"&gt;

&lt;meta http-equiv="CACHE-CONTROL" content="NO-CACHE"&gt;

&lt;meta http-equiv="expires" content="-1"&gt;

I'm no expert on browser cache issues, but it is becoming a problem. Does anyone have any tricks or fixes they've found that works beyond what I've got in place?

Thanks!
