I'm going to cache some RSS data from other websites to my server and update caches every 10 minutes. Should I use Asp.net system.web.caching or cache in database or file?
P.S: when a user requests a feed on my client application, my server downloads it from server. And in the next 10 minutes, if another user requests that feed, my server loads it from cache. There may be for than 100 feeds...
