Hi, I am using Drupal 6.6 with a single code base and multiple databases for multiple sites (one main + other sub domains). While the sites are working well, I'm having some difficulties with drupal based caching.
Whenever, I clear the cache of any one site (any one sub domain) by using the drupal core performance page clear cache button, I find that the cache of all the sites are getting cleared.
My question is: Is it possible to clear the cache of just one site (sub domain) without disturbing the main site and the other sub domain sites (multi site)?
I shall be grateful if anyone steps forward to help.
Many thanks in advance,

PS: Thanks to Drupal developers for creating a wonderful CMS.
