I assume you want to create an rss feed with the contents of your homepage, is that correct? If you don't experience any problems with updating your homepage every 10 seconds, then I see no reason why updating a feed every 10 seconds would cause you any trouble.
What sort of site so you have that is updated every 10 seconds? Do you have that much new content? Personally I would put the RSS on a linked page if I was you so that there is no risk of it affecting the refesh rate otherwise you will probably get display errors Paul
Maybe I misunderstood the question. If you're thinking about importing content via rss and displaying it on your page with an update every 10 seconds, that's going to generate errors for sure. Other websites won't allow you to fetch their rss content every 10 seconds.
I have a website, main page have new content every 10 seconds, almost auto, but not really auto (human). Now I want to add rss feed to main page, www.domain.com/feed.rss Is that ok?
Well, it depends on what you mean by "add rss feed to main page". Do you want to display the news items of an external rss feed on that page? Or do you want to make an rss feed from the content on your page that is updated every 10 seconds? If you want to use someone else's feed and display the contents of that feed on your web page, don't update it every 10 seconds. You will be blocked from that feed is you access it that often. You could cache the feed, so you don't have to fetch it every time your Webpage is updated. Besides, you only need to fetch it every time the feed is updated... If, on the other hand, you want to create a feed from your own content, then by all means update the rss feed as often as you update the content. I hope this helps. Good luck
