A method, within an application server, of modifying an intra-transactional cache, comprising:

• determining whether a copy of an original first data entity, accessed in the intra-transactional cache by a first client, has been updated;
• determining whether the copy is also within an inter-transactional cache;
• upon the copy not being within the inter-transactional cache, adding the copy to the inter-transactional cache;
• and
• after the copy has been added to the inter-transactional cache, removing, from the intra-transactional cache, the copy.
