Thanks for all your responses! I'm doing my own implementation of CookieSource and with a bit more of reading I learned how to hook to the WebRequestServicerFilter through hivemind. I got most of it working already.

I just create it as a service using my implementation and use that in my pages, components and services. You can do that until the framework provides what you want. I put it in my hivemodule like this: <service-point id="CookieSource" interface="com.elidoran.tapestry.CookieSource"> <invoke-factory> <construct class="com.elidoran.tapestry.DefaultCookieSource"> <set-service property="request" service-id="tapestry.globals.HttpServletRequest"/> <set-service property="response" service-id="tapestry.globals.HttpServletResponse"/> </construct> </invoke-factory> </service-point> To see the source changes I made you can check out the patch I provided for the standard classes here: http://issues.apache.org/jira/browse/TAPESTRY-419. I've been using the enhancement through many of the beta versions and had no problems. I use it in a persistence strategy that persists properties to cookies. The framework compiles and runs fine with the changes. ~eli Shawn Church wrote: Using Annotations, this has worked for me: @InjectObject("service:tapestry.request.CookieSource") public abstract CookieSource getCookieSource(); and then: getCookieSource().readCookieValue(name); or getCookieSource().writeCookieValue(name, value); One limitation is that writeCookieValue does not yet handle expiration dates (according to the TODO: in CookieSource.java). The second part of your question would involve hooking into one of the HiveMind engine services involved in handling each request (possibly Tapestry.request.WebRequestServicer). In Tapestry 3, it was a simple matter of overriding BaseEngine and implementing setupForRequest().
