Exclude Cart Block from Cache

How would one go about doing this? I looked into the Drupal API docs and found http://api.drupal.org/api/constant/BLOCK_NO_CACHE/6

which basically says to use something like

<?php
define('BLOCK_NO_CACHE', -1);
?>

in your module. Would I have to hack the ubercart core to do this? Is there a better way?

TIA,

That is for Drupal 6. Blocks in Drupal 5 do not get cached, unless you install the Block Cache module and then enable the cached version of a block.

I am using Drupal 5.7 but for some reason, I am showing that the block is cached. When the sites cache is enabled I am getting and I am browsing the store as an anon user and adding products to my cart, the cart block will show that I have products in my cart on certain pages while on other pages my cart block is empty.

Perhaps it is by my browser cache?? But why would it work just fine when the cache for the site is disabled?

Does this really not happen to anyone else? Does anyone use the Drupal Cache with their store?

What version of Ubercart are you running? This was a problem once, but was fixed many versions ago.

I use "normal" caching on our site and haven't seen anything like this. Do you have other cache modules enabled? Or anything server-side like APC or memcached?

No other cache modules enabled. Just using the normal cache settings and I have Aggregate and compress CSS files ENABLED. I'm not sure if there is anything additional server side. I'm on a shared server running on Hostgator, I could double check and make sure there is nothing else.

Any other ideas?

To be honest, I've seen this problem here and there and tried to address it in various ways, but I never really could reproduce it or strike gold on an across-the-board fix. If you hit on something, please let us know... somehow blocks do get cached along with the whole page for anonymous users, but it just doesn't seem to happen to everyone. Puzzled
