Question Call to joomla clean method after a new post is save/old post edited

I'm looking if there is a way to implement the joomla clean cache method after a new message, a reply or an edition is made in kunena fourm, without hacking any kunena core file.

I'm guessing. Are you using J! 1.5.x (where "x" is 22 or later)?

Is the symptom of the problem that you still see the ^NEW! indicator even though you have viewed or posted to a topic?

If you are talking about page cache, it was only designed to be used in static sites with no changing content. There's no way to disable it and cleaning up the cache is very slow task..

I'm using joomla 1.5.25, kunena 1.7.1. I see the "new" indicator some times, even though I have viewed the topic. But my question is not because of that.

In joomla 1.6+/1.7+ there is no expire time in the page cache plugin, so the cache clean method must be called from any extension after it makes any change, Am I correct?

Using this new page cache plugin in joomla 1.7+ I've expreimented a better (very high difference) performance.
I have kunena in a joomla 1.5.25 website. I've enabled the cache plugin with a very high expired time and the results are very good, I'm really happy. I've just coded a com_content plugin to trigger onAfterContentSave event and clean the cache after a new article is saved or an old one is edited. I've also configure a cron job to purge expired cache files periodically.

I'd like to do something similar with kunena applying the clean cache method after a new post is saved or an old one is edited, is kunena "plugiable" or I have to hack a core file??

As Matias wrote - and this is a good policy anyway for any website that has dynamically changing content (e.g. forum messages being posted) - you should not use caching on your website. Turn it off completely. Disable the cache plugin is a recommended.

As far as the "new" indicator is concerned, there is an issue that arose in J! 1.5.23 that causes a problem. See Problem with Recent Topics Tab; not refreshing .

I prefer use the cache plugin at this moment due the characteristic of my web: change content not very frequent and low registered users activity combined with high number of visits. If I turn off the cache I will have to host the web in a private server whith more resources, which is not currently affordable for me.

Thanks anyway.
