At least roundcube (v0.7.1 here) has some caching options:

------------------[excerpt from roundcubes main.inc.php]-------------
// Type of IMAP indexes cache. Supported values: 'db', 'apc' and 'memcache'.
$rcmail_config['imap_cache'] = null;

// Enables messages cache. Only 'db' cache is supported.
$rcmail_config['messages_cache'] = false;
-------------------------[end]----------------------------------------

But I don't know, whether this is the sort of caching you are referring to.
