Abstract
Using a counter of the Web server, a leave probability p, average value m and variance sof think time, and hit ratio r are calculated for a session data cacheinvolving a predetermined Web application. For a first reading of a group of reading plural session data proximate temporally, p, ma and s, and average value a of the number of data reading sessions in each group are defined. A computational expression setting meanssets a computational expression f(a)=a including p, m, s, r, p, ma and s, the computational expression for a fix point computing method having a variable a. A true value searching meanssearches an almost true value of a by the fix point computing method based on the computational expression f(a)=a. An estimation meansestimates ra based on a searched value of a.
