Hi, The link that I provided earlier on uses Feed2JS which in turn uses the MagpieRSS tool set (available on SourceForge). Magpie uses a cache that allows the user to specify an update period. At present I have the script on my site set to update the feed every 4 hours, or if there is a new feed. This type of method is the only one you should use, since as Bill states below, it is a waste of a providers bandwidth. Using the Feed2JS tool, multiple users would take the feed from my cache, unless a new article existed in the feed. So if more than 2 users have requested the same feed, they share the bandwidth from my server and not the provider.
MagpieRSS has the ability to set up CRON jobs to periodically update the cache by making the request for the content regardless of whether a web user has requested it. This I don't aggree with, because you should only request content when you actually want to use it. In choosing a tool to serve RSS to your site, you should make sure that it employs the 'cache' method of retrieval. If I had a 1000 hits per hour to my site, that is also a 1000 hits to the provider of the content that I am displaying. With the cache method, they would see a single hit from my site. The advantage of this to the provider is there content is still displayed on other sites, but not at the expense of their own bandwidth, so I would disagree with Bill on his blanket statement of only do it on your own feed. I would amend it to state only syndicate another providers content if your application caches the data.
