Fragment-based caching has been proposed as a promising technique for dynamic Web content delivery and caching. Most of these approaches either assume the fragment-based content is served by Web server automatically, or look at server-side caching only. There is no method of extracting fragments from an existing dynamic Web content, which is of great importance to thesuccess of fragment-based caching. Also, current technologies for supporting dynamic fragments do not allow to take into account changes in fragment spatiality, which is a popular technique in dynamic and personalized Web site design. This paper describes our effort to address these short comings. The first, DyCA, aDynamic Content Adapter, is a tool for creating fragment-based content from original dynamic content. Our second proposal is an augmentation to the ESI standard that will allow it to support looking up fragment locations in a mapping table that comes attached with the template. This allows the fragments to move across the document without needing to reserve the template.
