 CBindStatusCallback::Download and local cache


I need to download pictures asynchronously from particular web-site.
I use CBindStatusCallback<CPictureLoader> to manage asynchronous download.
One problem arises: when I try to download the same picture one more time
(from the same URL), CBindStatusCallback::Download retrieves it from remote
server again althogh this picture is already available in local cache (say,
pic[1].gif). After second download another file pic[2].gif with the same
picture appears in cache.

how can I force CBindStatusCallback to check local cache first?
Or are there any other ways to download data asynchronously with local cache
checking beforehand?
