Hello everyone,

I want to fetch some (5-10) RSS feeds from another server. I plan to  
fetch the RSS feeds asynchronously and store them on the hard disk  
every 30 minutes so I can read them from there on every request. (To  
treat the remote server with care and to avoid longer page generation  
time).

What is the best way to do that?

I think about starting a fetcher-thread on the start of my Rails  
application. I want to avoid cron jobs to keep everything in the Rails  
application.

Thank you!

So long  
Lennart K.
