I'm totally new to caching. Can you please help me with following requirement:
1. I need to display static html pages lying on ftp location whenever a user logs into the system.
2. These static html do not change for a month or two.
Thus I want to implement is, keep a cache of html pages on my web-app and check if it is 2 month old then download the latest copy from ftp otherwise display the file kept in cache to the logged in user.
