Hello,

Is there a way to programmatically clear the cache and/or force sh404sef to regenerate URLs?

We have a script that is called via Cronjob and creates items for the Joomla-extension Zoo from Yootheme (com_zoo).

The script deletes old items, recreates existing ones and creates new ones directly in the database.

The content is shown in the frontend in the overview page, but clicking through to items often leads to a 404-message.
After manually clearing the Joomla-Cache or purging the URLs, the content shows fine, so ideally, we'd like to automatically clear the cache and purge URLs after the script has run.

Kind regards, Stephan

After manually clearing the Joomla-Cache or purging the URLs

Those are 2 different things.The key point here is purging the Joomla cache, not purging the URLs. Until you purge the Joomla cache, the old links are displayed to visitors (because the page content has not been updated) and so they get 404.

When you purge the Joomla cache, then Joomla rebuilds the page use the new items, with their new URLs.

Removing the URLs from the DB would be useful, as they are just a waste if the items have been deleted, but that won't help solve this particular issue.

Instead of purging the URLs, which deletes everything and will cause 404s for other URLs as well until the URLs have been rebuilt, I would suggest:

1 - make sure the "URL disk cache" is disabled in sh404SEF config
2 - When you cron job deletes K2 items, it should also delete all URLs related to that item from the sh404SEF #__sh404sef_urls database table.

That way, you simply remove the URLs that won't be needed any longer, and keep the good ones. Again, your first problem is to clear the Joomla cache.
