AJAX-based web applications are enabling the next generation

of rich, client-side web applications, but today’s

web application developers do not have the end-to-end

visibility required to effectively build and maintain a reliable

system. We argue that a new capability of the

web application environment—the ability for a system

to automatically create and serve different versions of an

application to each user—can be exploited for adaptive,

cross-user monitoring of the behavior of web applications

on end-user desktops. In this paper, we propose

a live monitoring framework for building a new class of

development and maintenance techniques that use a continuous

loop of automatic, adaptive application rewriting,

observation and analysis. We outline two such adaptive

techniques for localizing data corruption bugs and

automatically placing function result caching. The live

monitoring framework requires only minor changes to

web application servers, no changes to application code

and no modifications to existing browsers.
