[Plugin: LINICKX LifeStream] RSS feed caching?

Hi Nick, hope you’re still watching this forum ??

Can you shed any light on caching, if any, of RSS feeds by run.php?

I’ve run into a new niggling problem, where the RSS feed is updated (I can see the new entries on a webpage that displays RSS e.g. this one https://www.netimechannel.com/OnlineRssViewer/ but when I execute run.php the feeds it displays are missing the latest entries. Some unspecified number of hours later it seems to work (sometimes as many as 24).

Is this due to caching, and can I turn it off?
