SharePoint Webpart Caching Considerations on Load Balanced Server

Could anyone tell me if its ok to cache my custom made webparts in a 开发者_StackOverflow中文版load balanced server environment?

Would caching cause any webpart dependencies on one server specifically or will the cache be stored across all servers?

I am caching list entries and user profiles returned from using UserProfileManager.

Caching is done in-memory per server, unless you build something to synchronize it across the servers.
