Not necessarily. Assuming it starts with nothing in the cache, the first request will cause CF to fetch the RSS feed and store it for two minutes. Any subsequent requests in those two minutes will read from the cache. After those two minutes, the next request will again cause CF to fetch the RSS feed and store it for two more minutes. > 2. Or, will it be sooner if the RSS feed on WordPress changes between the 2 > minute interval? No, it will not be sooner. CF has no way of knowing whether the RSS feed changed without fetching it, which would defeat the point of caching.
