Performance modeling and control of web servers
This thesis deals with the task of modeling a web server and designing a mechanism that can prevent the web server from being overloaded. Four papers are presented. The first paper gives an M/G/1/K processor sharing model of a single web server. The model is validated against measurements ands …

Disturbance Rejection and Control in Web Servers
An important factor for a user of web sites on the Internet is the duration of time between the request of a web page until an answer has been returned. If this response time is too long, the user is likely to abandon the web site and search for other providers of the service. To avoid this loss of …

Web servers, databases, and algorithms for the analysis of protein interaction networks
… and analysis of such PPI networks as well as web servers and databases for their public availability: 1. In many organisms, the coverage of experimental determined PPI data remains relatively noisy and limited. Given two protein sequences, we describe an algorithm, called Struct2Net, to …

Gurthang - A Fuzzing Framework for Concurrent Network Servers
… reachable from our computers and mobile devices. Web servers are one of the dominant types of computer programs that provide these services to the world by serving files and computations to connected users. Because of their accessibility and importance, web servers must be robust to avoid …

Universal web application server
The growth of the World Wide Web has in large part been made possible by the technologies that power it. These are the Web servers and Web browsers that many take for granted. Each has evolved to support the changing needs of users of the WWW from simple static text to highly interactive and …

Anomaly detection for HTTP intrusion detection : algorithm comparisons and the effect of generalization on accuracy
Network servers are vulnerable to attack, and this state of affairs shows no sign of abating. Therefore security measures to protect vulnerable software is an important part of keeping systems secure. Anomaly detection systems have the potential to improve the state of affairs, because they can …

Modeling virtualized application performance from hypervisor counters
… interpretable models. After training models for web servers and virtual desktops, we test generalization across different content. In our experiments, we found that our technique could distill small subsets of important hypervisor counters from over 700 counters. This was tested for both Apache …

Evaluation of Modified Condition/Decision Coverage in Testing a Web Server
… the Boolean expressions, without the overhead. Web servers are also state-based systems, and the purpose of this research is to determine whether the benefits of MC/DC also apply to these systems. In this paper, a unit-testing case-study on a typical web server Culture Object Management Web …

Pipelined Apache HTTP Server
Web servers often become overloaded with irregular surges in web traffic. Several techniques have been explored to cope with these overloads such as distributing load throughout different servers. This thesis presents Pipelined Apache HTTP Server, a modified version of the Apache Software …

Performance Evaluation of Web Archiving Through In-Memory Page Cache
… study proposes and evaluates a new method for Web archiving. We leverage the caching infrastructure in Web servers for archiving. Redis is used as the page cache and its persistence mechanism is exploited for archiving. We experimentally evaluate the performance of our archival technique using …

Protection Models for Web Applications
<p>Early web applications were a set of static web pages connected to one another. In contrast, modern applications are full-featured programs that are nearly equivalent to desktop applications in functionality. However, web servers and web browsers, which were initially designed for static web …

Dependability where the mobile world meets the enterprise world
… being used to interact with enterprise-class web services commonly hosted in virtualized environments. Virutalization suffers from the problem of imperfect performance isolation where contention for low-level hardware resources can impact application performance. Through a set of rigorous …
