Indeed. That means they will stay there until you delete them. The idea of using a cache is to prevent the database getting queried each time a page is viewed. It cuts down the overhead on the database.

You will need to write routines into your application that clear out the cache for data that is changing. So... any time you update a table clear out the cache.

Hi,, i already implement database caching class on application i was creating.. another question...

for example

i have

Code:

user 1

logged in on the website... the database query cache has been written with his informations in it..

then another user, lets say

Code:

User 2

has logged in, what will happen to the database query cache? will it overwrite the previous cache? thanks.. i was really confused...

sorry for my bad english.. :p

What setting in database.php defines the cache directory?

cachedir!
