Right now queries to data.southampton.ac.uk (eg. http://data.southampton.ac.uk/products-and-services/CupCake.rdf ) are made live, but this is not efficient. My colleague, Dave Challis, has prepared a SPARQL endpoint which caches results which we can turn on if the load gets too high, which should at least mitigate the problem. Very few datasets change in a 24 hours period.
setting the Expires header and enabling mod_cache in Apache httpd (or adding a Squid proxy in front of the HTTP server) works quite well in these cases. Best regards, Andreas.
