A multi-tier caching system and method of operating the same. The system comprises a first cache implemented in operating system or kernel space (e.g ., in memory managed by or allocated to an operating system) and a second cache implemented in application or user space (e.g., in memory managed by or allocated to an application program). Data requests requiring little processing to identify responsive data may be served from the first cache, while those requiring further processing are served from the second. The fir st cache may therefore store frequently requested data items or items that can be served in response to requests having different forms, qualifiers or other indicia. A content analysis engine determines which of the caches a data ite m should be stored in, based on an analysis of data requests or data items served in response to the requests, guidelines set by a system administrator , etc.
