This adds a new
waitingtrace that will be recorded by theHttpCachewhen the cache had to wait for another, concurrent request to the same resource to finish first.The information can be used for profiling - a high rate of
waitingrequests means there is a lot of concurrency, so that it might be beneficial to either speed up request processing or consider usingstale-while-revalidate.
