Just to double check, we would insert entry into the 'refresh queue' only if the page is requested and the page is soon-to-be-expired. once it is in the queue we would use above parameters to calculate the priority. Is this correct? or let me know If I have mistaken it. > see memcache_gdsf_algorithm() in mod_mem_cache.c for an implementation > of this, which assumes 'length' of request is related to the cost of > reproducing the request. > > the priority queue implementation is sitting in mod_mem_cache, and could > be used to implement the 'refresh' queue I would think. > I feel comfortable with mod-cache and mod-mem-cache code now. but we also need to start new thread/process for mod-cache-requester when server starts. I am not too sure how we could implement it. any pointers to the similar piece of code would be really helpful to me. Thanks, Parin.
