Modeling Request Routing in Web Applications

Minmin Han, Christine Hofmeister
2006 International Workshop on Web Site Evaluation, Proceedings of the  
The request routing in these web applications is an example of a pipeline architectural pattern: each request is processed by a sequence of components that form a pipeline.  ...  For web applications, determining how requests from a web page are routed through server components can be time-consuming and error-prone due to the complex set of rules and mechanisms used in a platform  ...  The three web applications differ in size, structure, and in use of underlying framework. We have validated the utility of request routing models using maintenance scenarios.  ...

Relating Navigation and Request Routing Models in Web Applications [chapter]

Minmin Han, Christine Hofmeister
Lecture Notes in Computer Science  
A navigation model describes the possible sequences of web pages a user can visit, and a request routing model describes how server side components handle each request.  ...  Routing model from a navigation model.  ...  The request routing model represents the request routes in a web application, so it is closer to the implementation: the elements in a request routing model directly map to the source code elements.  ...

Separation of Navigation Routing Code in J2EE Web Applications [chapter]

Minmin Han, Christine Hofmeister
2005 Lecture Notes in Computer Science  
The navigation routing code of a web application is the part of the code involved in routing a request from a web page through the appropriate components on the server, typically ending with the display  ...  But in J2EE applications this code is spread among a number of components, making maintenance costly.  ...  Another web application framework, Barracuda [1] , uses a more complicated event model, which is closer to the event model in swing applications. The events are hierarchically organized.  ...

Towards automated web application logic reconstruction for application level security [article]

George Noseevich, Dennis Gamayunov
2015 arXiv   pre-print
In this paper we propose an approach to web application modeling for security purposes that could help next-generation WAFs to adapt to specific web applications, and do it automatically whenever possible  ...  We aim at creating multi-layer models that adequately simulate various aspects of web application functionality that are significant for intrusion detection and prevention, including request parsing and  ...  In order to efficiently protect a web application, a firewall must also complete a transition from requests to actions and parameters, which requires a routing modeling of the process.  ...
