The default expiry time is in seconds so what is the largest value i can enter in this box? I'm running 3.4.1.
Because we are still on an old version and the way we run our site i alsways know when new content has been added or updated so can clear the cache invidually for those particular area's. So if it was possible we would like the cache to never expire but i'm not sure this is possible.
You cant get the cache to never expire. I would suggest picking a random big number and using that.
