CDN Caching and Live Auction Updates

-- HikaShop version -- : 6.5.1
-- HikaAuction version -- : 6.0.2
-- Joomla version -- : 6.1.2
-- PHP version -- : 8.4

Hello Team

I'm using HikaAuction together with a CDN.
While the CDN is working well for caching images, CSS, JavaScript, and other static assets, I believe it is also caching part of the auction data.

The issue I'm seeing is that when a user places a bid, other users who are viewing the same auction are not notified of the new bid or the updated auction status. The page appears to continue serving cached data until the cache expires or the page is manually refreshed.

My goal is to continue using the CDN for all static content to improve performance, but exclude the HikaAuction dynamic data (such as bids, current price, auction status, etc.) from being cached so that all users see updates immediately.

Any advice on how to do this please?

Thank you.
