It can be difficult to enhance, fix or extend legacy/closed-source web applications such as online catalogs without being able to alter the web application directly.

I will discuss using AHAH (Asynchronous HTTPRequest and HTML) as a technique for doing so and compare it to AJAX, proxying and SSI. Examples from the Seattle Public Library’s next generation online catalog will be presented. Performance and scalability concerns will also be covered, time permitting.
