Web servers become overloaded when one or several server resources are overutilized. In this paper we present an adaptive architecture that prevents resource overutilization in web servers by performing admission control based on application-level information found in HTTP headers and knowledge about resource consumption of requests. In addition, we use an efficient early discard mechanism that consumes only a small amount of resources when rejecting requests. This mechanism first comes into play when the request rate is very high in order to avoid making uninformed request rejections that might abort ongoing sessions. We present our dual admission control architecture and various experiments that show that it can sustain high throughput and low response times even during high load.
