A client requests a web page from a server including aggregated content comprising a plurality of content items from a plurality of content providers. The server provides content items to the client from a cache accessible to the server if any of the content items are stored in the cache, and requests any remaining content items from their respective content providers. The server receives responses from the content providers and stores any cacheable responses (i.e., content items) in the cache. Aspects of the invention apply to any content request from a client, for example, updating a client's widget with a content item.
