send-request server type pageid args &
send a request of page $pageid and type $type to $server. The only
request type allowed for a client is GET. $args has a format identical
to that of $attributes described in Http::enter-page.
start-session cache server & start sending requests of a
random page to $server via $cache.
start cache server & before sending requests, populate
$cache with all pages in the client's PagePool. This method is useful
when assuming infinite-sized caches and we want to observe behaviors
of cache consistency algorithms in steady state.
set-page-generator pagepool & attach a PagePool to generate
random page IDs.
set-interval-generator ranvar & attach a random variable to generate
random request intervals.
