Re: Lifecycle of a tapestry request and the MarkupRendererFilter
This may sound obvious but why not implementing a StreamResponseAdapter and extend it for your implementations ? Although a RequestFilter can be the right place for a front filter, or modify the ComponentEventResultProcessor that handle the StreamResponse (maybe more complicated) to automatically add headers... Many ways exist in fact :) Regards Christophe. 2009/10/15 Ian Petzer ian.pet...@ioko.com Hi, This is exactly how I am currently setting the headers, however I don't want to do this on an individual basis for all StreamResponses. What I'm looking for a is a filter or similar mechanism that can be used to post-process all responses irrespective of whether they are StreamResponse objects or the output from normal components with markup in a tml file. Essentially a filter like the MarkupRendererFilter that works on StreamResponses as well Thanks Ian -Original Message- From: cordenier christophe [mailto:christophe.corden...@gmail.com] Sent: 15 October 2009 15:31 To: Tapestry users Subject: Re: Lifecycle of a tapestry request and the MarkupRendererFilter What not using the prepareResponse of the StreamResponse Tapestry interface to set headers ? 2009/10/15 Ian Petzer ian.pet...@ioko.com Hi, We do actually have a load balanced caching system sitting in front our app server, however we control the caching behaviour by setting headers on the HTTP responses.

Regards Christophe. 2009/10/15 Ian Petzer ian.pet...@ioko.com Hi, I have been successfully using the CacheControlMarkupRenderer from the ioko-tapestry-commons http://tapestry.formos.com/projects/ioko-tapestry-commons/ library. This is a java class that implements the MarkupRendererFilter and Partial MarkupRendererFilter in order to apply caching headers to pages served by our application. This is all working wonderfully, however we now have a component which is returning a StreamResponse object out of the onActivate method of the component. This of course does not invoke the renderMarkup(MarkupWriter writer, MarkupRenderer renderer) method on the CacheControlMarkupRenderer as it is not markup. Is there an equivalent filter we could use that would enable us to set headers on the Response object but would be applied to both StreamResponse objects as well as the output from normal components with markup in a tml file.
