JSR286 explained : Caching
By karthiksudarshan on Aug 10, 2007
The public review draft of JSR 286 was released recently and the details of that can be found in Deepak's blog. Markup caching has been a part of JSR 168, but it had its limitations. JSR 286 addresses these limitations by introducing "Validation" caching and "Public" caching scope among other things. The details and the comparison of the JSR 168 and JSR 286 caching mechanism are available in my blog entry.
These improvements will be part of the OpenPortal Portlet Container soon and the performance gain thus obtained would truly be tangible :)
