Spidering
Spidering in biNu is the process whereby content is pre-cached from the server onto the client. The server intelligently parses each impression that is delivered to the client and determines which are the most likely navigations to occur next, and hence which pages or impressions will be visited next. The server then creates the impressions and sends them to the client, prior to them being requested.
Effects
The effect of this is that some page navigations appear to be instant, because the content has already been downloaded onto the handset. This technology further enhances the biNu user experience which is highly responsive and fast loading.
A minor downside is that some content may be sent to the client that is never viewed, however because of biNu's highly efficient compression and caching, the impact on data usage is very small.
