i have set caching website, expires after hour. problem if cache not exist , multiple users access website @ same time avoid users making same request @ same time. has impact on cpu usage @ 100% longer period of time. i using system.runtime.caching.memorycache. mvc asp.net application. i have thought of solution not sure how best implement it, thoughts are, one of many users first come in first, , start request , set flag fetching data , after more users come in shown no cache has been set before starting request check flag if request has been triggered. if has application should wait until response has come (is possible?), , use response cache. way 1 request sent , quicker response service , quicker response , cpu usage still quite low. please suggest alternative this, idea wrong can please advise? thanks
