I’m caching tweets on my site (with 30 min expiration time). When the cache is empty, the first user to find out will repopulate it.

However, at that time the Twitter API may return a 200. In that case I’d like to prolong the previous data for another 30 mins. But the previous data will already be lost.

So instead I’d like to look into repopulating the cache, say, 5 minutes before expiration time so that I don’t lose any date.

So how do I know the expiration time of an item when using php’s memcache::get()?

Also, is there a better way of doing this?

    In that case, isn’t this the better logic?

    • If the cache is older than 30 minutes, attempt to pull from Twitter
    • If new data was successfully retrieved, overwrite the cache
    • Cache data for an indefinite amount of time (or much longer than you intend to cache anyway)
    • Note the last time the cache was updated (current time) in a separate key
    • Rinse, repeat

    The point being, only replace the data with something new if you have it, don’t let the old data be thrown away automatically.
