All HTTP requests originated from clients will pass through the website gateway and be scheduled to the web server according to the QoS policies and the availability of the server resources. The website gateway first classifies the ining requests into different service classes by inspecting the contents of IP and HTTP headers. Then the scheduler decides which request can be fetched from the class queues and when to release it to the web server according to the QoS policies and the availability of the server resources, respectively. 44 Works Done Last Week (04/19/202004/25/2020) ?

For this, the token bucket mechanism is employed to decide when to release a request to the server. The current utilization of a server resource is represented by a token bucket. The size of a token bucket, . server resource capacity, and the amounts of resources (tokens) a request needs is estimated from the results of the server probing. When a request is released, the token buckets discard tokens. Conversely, when an HTTP response finishes passing through the gateway, . the server resources are released, the discarded tokens are returned the buckets. 47 Works Done Last Week (04/26/202005/02/2020) ?

The probers recursively scans the web pages on the same sever link by link until all the web pages have be scanned. The probed URL, response size and the amounts of required resources of each page will be recorded in the web page table. Note that the response size of a page recorded in the table is chosen from a number close to the actual probed responses size. 50 Works Done Last Week (05/03/202005/09/2020) ? NBL: ?

However, the server capacity is finite, it cannot processes unlimited number of request at a time, or the userperceived latency would be longer. So the scheduler should release requests according to the availability of the server resources. In our work, we employ token bucket mechanism to throttle the speed of releasing requests. Each token bucket stands for the current utilization of a server resource. When a request is released, the token buckets discard tokens. On the contrary, When an HTTP response finishes passing through the gateway, . the server resources are released, the disc
